Question 1188221
How do convert Sq rt of (-27a^10) to the power of k/3 into simplest radical form? 
------------------
{{{(sqrt(-27a^10))^(k/3) = (a^5*3*sqrt(-3))^(k/3) = (a^(5k)*3^k*sqrt(-3))^(1/3) = (3^k*a^(5k)*sqrt(-3)^k)^(1/3)}}}
= {{{root(3,(3^k*a^(5k)*sqrt(-3)^k))}}}
========================
Sometimes "simplest" is a matter of opinion.
