Question 64096
The square root of U to the 3rd power divided by the cubed root of U?
Rewrite using fractional exponents.  The powers are the numerators (top) and the indexes are the denominators.
{{{U^(3/2)/U^(1/3)}}}  subtract the exponents when dividing.
{{{U^(3/2-1/3)}}}
{{{U^(9/6-2/6)}}}
{{{U^(7/6)}}}
Which is also the sixth root of U to the seventh power.
Happy Calculating!!!
