Answer 1

The square roots of 144 are:

A. 24

D.144 ^1/2

F.12

144 is a perfect square, so the square root of 144 is a positive and negative value of 12, 24 and 144^1/2.

Option B 6 and C -12 are not square roots of 144 because 6^2 = 36 and -12^2 = 144 .

Option E -144^1/2 is not a real number, because the square root of a non-negative number is always non-negative.
