This is a question from Manhattan foundation of math
as we have a division operation, so the sign should be negative and we subtract exponents (3-1)
so we are left with - 2^2 which is equal to 4
However, in the book (the correct answer) is -4
they did: -2^3 = -8/2 = -4
I understand their way, but what is wrong with what I did?
Obviously, I did something wrong cause I didn't get the same answer...
The numerator in the question is -2 and denominator is +2. what you have done is subtracted exponents of different bases.
It should be - [ (-2)^ (3-1)] = - [(-2)^2] = -[+4] = -4
hope this helps
