Question 623479: Please help! I dont know what to do next! Simplify.
+%284x%2Fy%5E3%29%5E-3+
Here is what I have so far.
+%284x%29%5E-3%2F%28y%5E3%29%5E-3+
Reduces to:
+4x%5E-3%2F%28y%5E3%29%5E-3+
Reduces to:
+4x%5E-3%2Fy%5E-9+
That is what I have so far, what do I do next?

You can put this solution on YOUR website!
+%284x%2Fy%5E3%29%5E-3+
the reciprocal gets rid of the neg exponent
+%28y%5E3%2F4x%29%5E3+ = +%28y%5E9%29%2F%284%5E3x%5E3%29+ = +y%5E9%2F%2864x%5E3%29+

I think you are making this harder than it is,
remember you have to raise 4 to the third power also, but it looks like you know what you are doing
