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.
