Wei Kit knows that roots can be re-written using exponents. Study his examples below:

EXAMPLES: $\sqrt { x } = x ^ { 1 / 2 }$      $( \sqrt [ 5 ] { z } ) ^ { 2 } = z ^ { 2 / 5 }$      $\sqrt [ 3 ] { m ^ { 2 } } = m ^ { 2 / 3 }$

Use Wei Kit's method to rewrite the following radicals using exponents.
