So now where is your detailed work - the one you feel is most promising.In the first problem, in the denominator,
Is it:
\(\displaystyle \left( x^{-3}\right) * \frac{2}{3} \)
or
\(\displaystyle \left( x^{-3}\right) ^{ \frac{2}{3}} \)
Please share your detailed work - the one you feel is most promising. That will give us an idea about where to begin to help you.
