Answer:

\frac{12 {z}^{ 3} {y}^{2} }{5 {x}^{ 2} }

Step-by-step explanation:

We want to simplify:

\frac{36 {x}^{ - 2} {y}^{2} }{15 {z}^{ - 3} }

The trick is that when a negative index in the numerator comes to the denominator , it becomes positive.

The vice-versa is also true.

That is:

{a}^{ - n}  =  \frac{1}{ {a}^{ n} }

and

{a}^{n}  =  \frac{1}{ {a}^{ - n} }

We simplify to get:

\frac{12 {z}^{ 3} {y}^{2} }{5 {x}^{ 2} }

The last choice is correct.
