Remember that a positive times a negative is a NEGATIVE.
And that a negative times a negative is a POSITIVE.
So in the case of something like:
But multiplying that by -3 is a positive times a negative.
So that will give us a negative, and 9 x 3 = 27
So that gives -27
So what we can conclude is that when the exponent is an even number, we will always have a positive answer.
If the exponent is odd, the answer depends on what we started out with.
-3 or -4 or -5, etc to any odd power will ALWAYS give a negative answer.
But any value to an even power will ALWAYS give a positive answer.
A positive value to an odd power will give a postive answer.
A positive value to any power(even or odd, positive or negative) will ALWAYS be positive.
