SHORT ANSWER

Write each of the numbers 1, 4, 9, 16, and 25 as a base raised to the

step by step:

The square of a number is the number you get ehen you multiply that bumber by itself. so if n is a number then nxn = n2 is the 'square of n' it is called that because the area of a square whose edge lengh is n units is n2 square units

perfect square numbers are the numbers which are ths squares of the positive integers
