How do you solve square roots....plz give me some examples
mamaluj [8]
Square roots are numbers.
if you multiply a number by itself then it is a square number. if you are looking to find a square root of a number, a square root is finding the number that was squared (multiplied by itself) to make the other number. For example,
the square root of 4 = 2
2×2 =4
Another example, square root of 64 is 8
8×8 is 64 :)
