Math Help - Simplifying an Expression

1. Simplifying an Expression

How would you go about doing this ?
Would it equal x^ ( 2a - [ (3a+b)/2 ] ) ??

2. Re: Simplifying an Expression

That is absolutely right

3. Re: Simplifying an Expression

Surely you can simplify that a lot, for starters...

\displaystyle \begin{align*} \frac{\left( x^a \right) ^4}{x^{3a+b}} &= \frac{x^{4a}}{x^{3a + b}} \\ &= x^{4a - \left( 3a + b \right) } \\ &= x^{a - b} \end{align*}
