When the square root of a number or term squared is taken, the answer simply comes out of the radicand.
Sample:
sqrt{(x + 1)^2} = x + 1
Can this be the reason? See below.
sqrt{(x + 1)^2} = [(x + 1)^2]^(1/2).
The exponents become 1:
Exponents: 2 (1/2) = 1
Anything to the first power equals itself.
Correct?
