Question

Write your answer with a positive exponent only.
(y^-4z^7)(3x^3y/z^-1)^-2

Answer 1

hwy, dumbo -- it said positive exponents only!
(y^-4z^7)(3x^3y/z^-1)^-2
= y^-4 z^7 * (z^-1/3x^3y)^2
= z^7/y^4 * 1/9x^6y^2z^2
= z^5 / 9x^6y^6

Answer 2

(3x^3y/z^-1)^2 / y^4z^7

Answer 3

My apologies for missing that! Thank you for providing the correct answer with positive exponents only.
