answer is -64 because (-4)^3 means you’re multiplying -4 THREE times.
it goes -4 x -4 x -4 = -64
and remember that if you have a negative number and have an ODD number as an exponent, you will always end up with a negative number as your answer. this is because -4 x -4 is 16 that’s positive but then 16 x -4 is -64
so if you had a negative number and had an EVEN number as an exponent, you would end up with a positive number.
so your answer therefore is -64
