The square root of 64 is 8. Square rooting is the process of finding a number when you multiplied by itself will give you the radicand(number inside the square root sign).

It would be helpful to those who is starting to learn math to memorize the table below.

2x2 = 4 6x6 =36 10x10 = 100 ....

3x3 = 9 7x7 = 49 11x11 = 121 .....until

4x4 =16 8x8 = 64 12x12 = 144 20x20 =400

5x5 = 25 9x9 = 81 13x13 = 169

The square root of number a is a positive or negative number b such that b^2 = a.

In this case, the square root can be found by simplifying radicals:

sqrt(64) = sqrt(2*2*2*2*2*2) = 2*2*2 = 8

However, based on the aforementioned definition, you can conclude that the square root of 64 = +or- 8

What is the square root of 64?

? 64 = 8 OR -8

since (8)^2 = 8 * 8 = 64

also (-8)^2 = ( -8 ) *( -8 ) = 64
