Question 51682
<pre>
I have the answer in the back of the book. Still having trouble getting there.

4^2/3 * 6^2/3 * 9^2/3

Have tried squaring 4 and then taking the cubed root but don't get good numbers.

The book says answer is 36?????
===============================
{{{highlight(matrix(2,1, " ", 4^(2/3) * 6^(2/3) * 9^(2/3)))}}} = {{{matrix(2,1, " ", (4 * 6 * 9)^(2/3)) = 216^(2/3) = (root(3, (216)))^2 = (6)^2 = highlight(36)}}}</pre>
