What are square roots used for?
If you have a square root of a number, that means that your "square root" squared (multiplied by itself) will give you your original number. For example: * The square root of 4 is 2. * 2 x 2 is 4.
If you have a number being multiplied by a square- root and it is squared do you square both numbers?
The square-root and the square cancle each other out so you will only be left with the number Example: √2² Would become 2
Opposite of square root?
Squared. E.g the square root of 4 is 2, and 2 squared is 4.
How do you square a square root?
The square of any square root is equal to the number itself. For example, the square of the square root of 2 squared is equal to 2. The square root of 10 squared is equal to 10.Similarly, the square of the square root of 2 is equal to 2.

What is the square root of 2 multiplied by the square root of 2?
The answer is 2. The square root of 2 (about 1.414) is the number that when squared (multiplied by itself) is equal to 2 --(if you multiply 1.414 times itself, it is actually 1.999). sqrt 2 x sqrt 2 = (21/2)2 = 21 = 2

Formula for surface area of a pyramid?
The surface area is length times width plus length. Then you find the square root of the width divided by two and then squared. You add this to the height squared plus the width. The width is multiplied by the square root of 1/2 squared plus the height squared.
