Iwill mark brainiest how do i answer this one? 1/32768 is not the answer

The answer you would be looking for would be 8^-5.

This is because when you multiply the same number with a different exponent, you keep the number the same instead of multiplying it (8 instead of 64), and you add the exponents (-7 + 2 = 5). Thus giving you an answer of 8^5.

I hope this helps!

Ican't do any of the other stuff, but i can get you started. the answer, i believe, is $2.50.
