To multiply variables with negative expontents it gives the answer that is,  

z ^ 4 / x ^ 3 y ^ 3

Step-by-step explanation:

If we have a question like this,

x^-3 y^-2 z^4,

In this if the power is negative, we write it in upon.

It will be positive means if it is x ^ -3,

Then we write it as 1 / x ^ 3 after that we have y ^-2 that makes it positive by 1 / y ^ 2.

We have z 4 that is already positive hence,

First we have to make this positive by writing it in,

Fraction form 1/x3 * 1/y2 * z4

= it will be z ^ 4/x ^ 3 *y ^ 2

Therefore the answer will be = z ^ 4 / x ^ 3 y ^ 3
