With positive fractional exponents, you convert the numerator to the power.

Fractional exponents translate into radicals, and negatives behave in the same way as exponents.
Generally, you can manipulate fractional exponential expressions in the same
way that you manipulate other fractions. Consider the following expression:

allows you to perform the
multiplication operation by adding the two exponents. This gives you
6
, which
you can then reduce and convert to a radical form.
