Simplify the Expression by Using the Properties of Rational Exponents $$\left( \frac { 2 z ^ { - 2 / 3 } } { t ^ { 5 / 3 } } \right) ^ { - 3 }$$

Short Answer

Simplify the expression by using the properties of rational exponents. Write the final answer using positive exponents only. $$\left( \frac { 2 z ^ { - 2 / 3 } } { t ^ { 5 / 3 } } \right) ^ { - 3 }$$
