Hello,

I have a problem that I have a lot of trouble with, and I've tried to simplify, but I don't get it right. I would appreciate the help!

Here it is: 256/9x^5 raised to the nth root of 4
I need to rationalize the denominator of 9x^5

I hope I explained myself well. Thanks for the help!

I would appreciate if you could show step by step simplifying- the main trouble I'm having with is rationalizing the x^5...

I am sorry, what do you mean by nth root of 4?

Is this it:

$\sqrt[4]{\frac{256}{9x^{5}}}$

The fourth root of 256 is 4, because $4^{4}=256$

Please clarify before I go any further.

Maybe the problem is this:

$<br /> \left ( \frac {256} {x^5} \right ) ^ {( 4 ^ {1/ N} ) }<br />$

But as Galactus says - please clarify.

Hello,
Thanks for the reply! I apologize, I wasn't sure how to write the problem in words...

And yes, the problem is the one galactus wrote.
