Problem 9
When you simplify ![$\left[ \sqrt [3]{\sqrt [6]{a^9}} \right]^4\left[ \sqrt [6]{\sqrt [3]{a^9}} \right]^4$](http://latex.artofproblemsolving.com/5/8/4/58445c91c8f5fb52978a56369a3c2e6d48dcd1b8.png)
, the result is:
Solution
This simplifies to
![\[(a^{\frac{9}{6}/3})^4 \cdot (a^{\frac{9}{3}/6})^4 = (a^{\frac{1}{2}})^4 \cdot (a^{\frac{1}{2}})^4 = (a^2)(a^2) = \boxed{a^4}\]](http://latex.artofproblemsolving.com/2/0/3/203b6f8ba129e737d1542bd14f877189ba474876.png)
The answer is
