This video in the Education category will show you how to simplify radicals before adding or subtracting. By doing this you will find all like radicals which will then ensure that you have all radicals in the simplest form. Let’s say you want to subtract square root of 45 from 3 square roots of 20. Now square root of 45 can be written as square root of 9 x square root of 5. Because, 9 and 5 are factors of 45. Similarly, 3 square roots of 20 can be simplified to 3 x square root of 4 x square r...
When you need to compute the square root of a number you can do it by breaking it into perfect squares. When you can split the given number into small perfect squares you can cancel out the square root of the expression to the square of the perfect squares. You cannot always write the number inside the square root as a perfect square, but try to write this number as a product of a perfect square and another number. Now you can pull out the perfect square out of the radical and leave the remai...
This is a mathematical instructional video on how to find the least common multiple. Let us now find the least common multiple for 25, 100, 18.

It is easy to find out that right triangle is only half of the square. And again there is a rectangle with a triangle shaded in red color. The red triangle is half the area of the rectangle. But to calculate just the area of triangle, we can calculate the area of the rectangle whose area is length times width. When we have a rectangle with its length and width as 4u and 2u respectively then the area of that rectangle will be equal to 8u(squared). But we already know that the triangle is half ...
An alternative to origami, here’s a very easy paper design strp icosahedron by Heinz Strobl. Here's a very easy icosahedron to origami. For the strips, use an A4 format paper and cut it in the middle lengthwise. Do so to get 8 strips and then fold strips of 6 squares. It requires 20 strips of 6 squares for the triangles and 30 strips to knot them together (strips of 5 squares also work). Only the knotting strips will stand out, but it is still better to use two colors. You can make a bigger m...
In this video, we learn how to finish a crochet never ending granny square. There is a spiral effect happening in this, because there is no place that is stopping, it's going in a continual circle. To finish one of these, you will see that the corners should be perfect. But, you will need to choose one corner to finish it off at. Go across, then choose a side to stop at. Then, chain over and double crochet in. When you come across with another color, you can weave in the end so that you can't...
Equations involving square roots are difficult to solve because of the complexity involved in performing operations on the square root terms. But you can follow a series of steps to solve these problems easily. To solve these kind of problems first isolate the square root term on one side of the equation and the non square root terms on the other side of the equation. Now in the next step square both sides of the equation. This gets rid of the square root on the left hand side and the equatio...

Every Sudoku game starts with a few of the squares filled in. The more squares that are filled in the easier it is to play. As you fill in the squa...
In this video the instructor shows how to simplify radicals. A radical is nothing but another name for a square root. To find the square root of a simple number the first thing that you need to do is factor it. If you need to compute the square root of a number, you first need to find a number which multiplied by itself gives the original number under the root. For example, to find the square root of 9, you need to find a number which multiplied by itself gives 9. Here the answer is 3. When 3...
Professor ElvisZap teaches you how to stretch shift and reflect the graph of a square root. A square root function is the opposite of a squared function. You start with y=square root of (x-1) it becomes 0<=x-1. then 1 <=x. You use the graph and solve it as you would for any function using small values first, then you have y=square root of x - 1, the domain 0<=x. This shifted the graph down 1 unit. 0=square root of x - 1, 1=square root of x, 1=x. Then the range is [-1 + infinity). Continue in ...
In this video the instructor shows how to solve quadratic equation by the square root method. The square root property of equations states that if k is positive and a*a = k, then a is equal to square root of k or -1 times the square root of k. So to solve a quadratic equation by square root property first get the equation in the form of a*a = k. Now apply the square root property explained in the previous step to get the result. The instructor now demonstrates these concepts by solving some e...
In this video the instructor shows how to sketch the graph of x squared and square root of x. The first equation is the x squared which is y = x * x. Now to sketch this take a sample values of x and substitute in the equation to get the value of y. Similarly find the set of points for the equation. Finally plot these points and sketch this graph which is in the form of a parabola. The curve is in the form of alphabet 'U' with its vertex at the bottom. Now similarly take the square root of x e...
Here we look at squaring expressions that involve radicals because people tend to make some common mistakes while solving such expressions. Take 5 times the square root of y quantity squared, the answer here is not 5y. Here's the reason, square means to multiply something with itself so the square of 5 root y would be 5 root y into 5 root y. So 5 x 5 is 25 and under root y into under root y equals just y so the answer will be 25y.
robichaudd teaches you how to simplify square roots. When you're dealing with variables, even powers and you want to find out the square root of it, you follow the process. Divide the power by the root, which is two, because it's a square root, that gives you what comes out. If we have square root of x squared, the result would be x. So the square root of x to the 6 is x cubed. You simply divide the power by two, since we are dealing with square root. Then square root of 36 times x square is ...

When you open the paper back up, you will have a square sheet of paper that you can fold. You fold all the corners of your square in to the center. Then you flip it over to the back and repeat. Once do...
This is the video about how to evaluate square roots. The square root of a number is a number that you can square to get it, that is, a number that you can multiply by itself to get the number. So, 2 is a square root of 4, because 2 x 2 = 4, and 3 is a square root of 9, because 3 x 2 = 9. (-2) x 2 is also 4 and (-3) x 2 is also 9. Numbers that have square roots always have two, a positive one and a negative one, but the square root symbol means only the positive one, so we can have one answer...

In this tutorial, we learn how to understand the properties of a square in Geometry. The four angles on the inside of a square have to be right angles. All but be 90 degrees and add up to 360. A square has four equal sides, which you can notate with lines on the sides. The diagonals of the square cross each other at right angles, so all four angles are also 360 degrees. Diagonals have to be equal in length to each other as well. Once you better understand this, you will be able to learn more ...

There definitely exists logic behind calling these fuzzy crochet squares granny squares. After all, the cozy texture and delicate, retro motif do remind us of Sundays visiting Grandma while she served us tea and sandwiches and she knitted the day away.
Radicals are square roots which are not integers; the square roots of 2 or 3 are examples of radicals. The presenters show simple ways of how to add and subtract such radicals. They explain that by using the method of factoring, the addition or subtraction is made very easy. If the square root of 8, for instance, is in some addition sum, it can be factored into the square root of 4 times the square root 2. Since we know that the square root of 4 is 2 this can be simplified to be 2 times the s...
