48 x^3 y^2 z^16 divided by -10 x^2 y^4 z^15 ^ = To the power of

From 48 x^3 y^2 z^16 / -10 x^2 y^4 z^15, I got:

-48/10 * x * 1/y^2 * z

so:

-4.8 * x * z * 1/y^2

therefore, my answer to this question was:

-4.8 x z / y^2

(I may not be correct, it's just my answer. It's been a year or two since I learned algebra)
