Question 475769
Simplify by taking roots of the numerator and the denominator.
 Assume that all expressions under radicals represent positive numbers.
3V 8x^5/y^3 
:
Assume you mean the cube root here
{{{3sqrt(8x^5/y^3)}}}
We can write it:
{{{3sqrt((8x^3*x^2)/y^3)}}}
Extract the cube roots
{{{(2x)/y}}}*{{{3sqrt(x^2)}}}
