I am sorry if I was unclear. Thanks for the help.
so we need to use our laws of expoents

\frac{x^{\frac{1}{2}}}{(x^\frac{3}{4})(x^{-2})} add exponents in the denominator

\frac{x^{\frac{1}{2}}}{x^\frac{-5}{4}} subtract the exp for the division

x^{\frac{1}{2}-\frac{-5}{4}}=x^{\frac{9}{4}}

for the next we distribute

8x^{8/5}(x^{11/5}-9x)=8x^{19/5}-72x^{13/5}

good luck.
