The first thing I would do is change \[\sqrt[3]{4^{4}}\] into a rational expression
OpenStudy (anonymous):
Do you know how to do that
OpenStudy (jenniferjuice):
4^3/4 ? LIKE THIS?
OpenStudy (jenniferjuice):
sorry forgot caps was on

It would be \[x ^{\frac{ 4 }{ 3}}\]
OpenStudy (jenniferjuice):
oh .
OpenStudy (anonymous):
So now you have \[x ^{\frac{ 4 }{ 3 }(5)}\]
OpenStudy (anonymous):
Do you know how to solve that?
OpenStudy (jenniferjuice):

OpenStudy (ipwnbunnies):
You're on the right track. But keep the exponent as a rational expression (a fraction) instead of a decimal.
OpenStudy (jenniferjuice):

OpenStudy (jenniferjuice):

OpenStudy (jenniferjuice):
or add...?
OpenStudy (ipwnbunnies):
Yesh, multiply them.
\[x^{\frac{4}{3}}\] is being raised to the fifth power. So, you'll have to multiply the powers.
OpenStudy (jenniferjuice):
i got 6 2/3 ..? is it right?
OpenStudy (ipwnbunnies):
Don't turn it into a mixed fraction. :3
OpenStudy (jenniferjuice):
okay .. then i would have 20/3
