Question 322968
{{{x^(1/6)*y^(1/4)*z^(1/2)}}}

in order to have a single radical expression you need to have the same index (denominator) so re-write the exponents with the LCD of 12.


{{{x^(2/12)*y^(3/12)*z^(6/12)}}}  x^(2/12)*y^(3/12)*z^(6/12)

since the index is 12 re-write as 
{{{root(12,x^2y^3z^6)}}}
