The principal sq. root of a number can be a positive integer.
However, -5^2 is actually -25.
(-5)^2=25.
However, -5^2 is actually -25.

No.
It really depends on how the question is phrased.
√(25) = 5
But if you say
x² = 25 ... then
|x| = 5 ... and
x = ±5
The rule is
√(x²) = |x|

-
Yes, multiplying a negative by another negative cancels out the negative sign.
-
-5x-5=25 and 5x5 = 25. Every +ve number has 2 square roots.
-
Yes, but it's written (-5)^2
-
Yes.
