(x+7)^(-1/3)-(x-+7)^(-2/3)

OpenStudy (anonymous):

can you rewrite it?

OpenStudy (anonymous):

^(-1/3) and ^(-2/3) are the exponents but they are fractions. i have to factor and simplify.

OpenStudy (anonymous):

whats x-+7?

OpenStudy (anonymous):

sorry, (x+7)

OpenStudy (anonymous):

\[(x+7)^{-1/3}-(x+7)^{-2/3}\]

OpenStudy (anonymous):

\[= (x+7)^{-1/3}(1-(x+7)^{1/3})\]

OpenStudy (anonymous):

is that a fraction? \[(x+7)^{-1/3}-1/(x+7)^{2/3}\]
