Simplify the following

OpenStudy (anonymous):

\[\huge (\frac{ a+1 }{ a^{2/3} - a^{1/3} +1 }- \frac{ a-1 }{ a-a^{1/2} })^{10}\]

OpenStudy (anonymous):

just the inner thingy how to simplify it is so ugly

OpenStudy (michele_laino):

please use the subsequent identity, in order to decompose the numerator of first term: \[(x ^{3}+1)=(x ^{2}-x+1)\]

OpenStudy (anonymous):

a = a^{1/3}^3

OpenStudy (anonymous):

cool

OpenStudy (michele_laino):

oop.... sorry: \[x ^{3}+1=(x+1)(x ^{2}-x+1)\]

Parth (parthkohli):

\[a - 1 = (\sqrt a + 1)(\sqrt a - 1)\]And the denominator is \(\sqrt a (\sqrt a - 1)\).

OpenStudy (anonymous):

yeah thanks

OpenStudy (michele_laino):

\[x=a ^{1/3}\]

OpenStudy (michele_laino):

Thanks! @No.name @ParthKohli

OpenStudy (anonymous):

\[\huge (a^{1/3} - a^{-1/2} ) \]
