--5x-5=25 and 5x5 = 25. Every +ve number has 2 square roots.-Yes, but its written (-5)^2-Yes.......

5 is the principle square root of 25. Negative 5 is also a square root of 25.

"The" square root of 25 is often meant to be the principle square root.

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

-
Yes, because -5 * -5 = 25

The person saying you can't take the square root of a negative number should notice 25 is not a negative number.

-
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|

I hope this helps you!|

No. The square root of a negative number is an imaginary number.

-
Yes because a negative times a negative = positive. +5 / -5 Are the square roots of 25

When looking at square roots the (-) is taken out of count, for example -5 * -5 DOES in fact equal 25 so yes -5 can be the square root of 25

-
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.
