Determine which number is a perfect square.

Solution:

In order to determine if the number is a perfect square, we must simply take the square root of the number. This can be done by enclosing a square root sign or raising the number to ½

A. (127)^½
= 11.27

B. (100)^½
= 10

C. (13)^½
=3.6

D. (102)^½
=10.09

It can be seen the 100 is a perfect square number since when we take its square root, the result is a whole number.

Final answer:

B.
