Question

is 98 a perfect square ? explain why

Answer 1

A perfect square is a number which can be written as the product of two identical numbers:

16, 25, and 36 are prefect squares because:

4*4 = 16
5*5 = 25
and
6* 6 = 36

With that in mind, you should be able to continue multiplying numbers until you find your answer. :)
