Answer:
Dividing a number by itself just gives the number 1. To find the square root of a number you are looking for a divisor that will divide into the dividend giving a quotient number that is equal the divisor. For example the number 16 has a square root of 4 because 4 x 4 = 16.

Answer:
Squaring, which we learned about in a previous lesson (exponents), has an inverse too, called "finding the square root." Remember, the square of a number is that number times itself. The perfect squares are the squares of the whole numbers: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100
