Question 1017150
how do you find the product:

(7 CUBED ROOT 6)(3 CUBED ROOT 9)
============
It's cube root, not cubed root.
----------
When the index is the same, 3 in this case, multiply what's under the radicals.
{{{7*root(3,6)*3*root(3,9) = 21*root(3,54)}}}
= {{{21*root(3,27)*root(3,2)}}}
= {{{21*3*root(3,2)}}}
= {{{63*root(3,2)}}}
