You can put this solution on YOUR website! 42^1/3
------- all raised to the 2 power or squared is how I interpret this
6^1/3
This is 7^(1/3) power^2
That is 7^(2/3)
That can't be simplified but is about 3.66
--------------------
If it is
42^1/3
--------
(6^(1/3))^(2)
Then it would be 42^(1/3)/6^(2/3), and this can be rewritten but not simplified.
