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