You can put this solution on YOUR website! You didnt specify, but I imagine you would like to simplify this expression.
Lets start with the -243.
We can think of this as
We know that the cubed root of -27 is -3.
So we can take out the -3 and leave the 9 under the radical
Next we look at the .
We know that the cubed root of is x, so that can come out as well.
Finally we lookat the .
We can think of this as
From this we know that the can come out 3 times as with 1 remaining under the radical.
This is the most this expression can be simplified
I hope this helps.
Good Luck!
