3(1+x)^1/3 - x(1+x)^-2/3 / (1+x)^2/3 I need help. Please show steps please?
\[3(1+x)^{2/3}-x(x+1)^{-2/3}/(1+x)^{2/3}\]
they cant show the negative in x(x+1)^-2/3. can anyone please help me solve it?
\[3(1+x)^{\frac{2}{3}}-\frac{x(x+1)^{-\frac{2}{3}}}{(1+x)^{\frac{2}{3}}}\]
\[3(1+x)^{\frac{ 2 }{ 3 }}-\frac{ x(x+1)^{-\frac{ 2 }{ 3 }} }{ (1+x)^{\frac{ 2 }{ 3 }} }\] =\[\frac{ 3(1+x)^{\frac{ 2 }{ 3 }+\frac{ 2 }{ 3 }}-x(x+1)^{-\frac{ 2 }{ 3 }} }{ (1+x)^{\frac{ 2 }{ 3 }} }\]
That is correct so far.
sorry if you misunderstood, but the whole thing is divided by (1+x)^2/3. sorry if that was not clear.
AH okay. @Mertsj You do that for @asapbleh
I'm going to take a rest.
\[3(1+x)^{-\frac{1}{3}}-x(1+x)^{-\frac{4}{3}}=(1+x)^{-\frac{4}{3}}[3(1+x)^{\frac{3}{3}}-x]\]
\[(1+x)^{-\frac{4}{3}}(3+3x-x)=(1+x)^{-\frac{4}{3}}(3+2x)\]
What were you supposed to do with this?
It was a homework problem. it says "simplify the expression. (This type of expression arises in calculus when using the quotient rule."
There are several different forms you could put it in. That one is probably as good as any.
ok, thankyou very much!
