@satellite73 @sammixboo @ihateschool18

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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):

ummmmmm i got 6.66666666666667 but its probably wrong :/

OpenStudy (jenniferjuice):

@ihateschool18

OpenStudy (jenniferjuice):

@iambatman @iPwnBunnies help please?

OpenStudy (ipwnbunnies):

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

OpenStudy (jenniferjuice):

okayy gimme a sec to solve it

OpenStudy (jenniferjuice):

do i multiply it?

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

OpenStudy (ipwnbunnies):

Yesh. ^.^ Exponents are never written as mixed fractions. :3 Gewd job.
