Find a real number between (-2)2 and square root of 25

(-2)2 = 4

square root of 25 - 5

a) -3
b) 3.998
c) 4.225

My answer is a. Am I correct.

(-2)2 = -4 (you said positive 4, I don't know if it was a typo, or...)

Having said that, all should be correct... I'm confused. Did you copy the question correctly?
