Question

If y’all could figure this one out!!

Answer 1

`\cfrac{5}{√(x)}-\cfrac{9}{(√(x))^9}\implies \cfrac{(√(x))^8(5)~~ - ~~(1)(9)}{\underset{\textit{using this LCD}}{(√(x))^9}} \implies \cfrac{5(√(x))^8-9}{(√(x))^9} \\\\\\ \cfrac{5√(x^8)~~ - ~~9}{√(x^9)}\implies \cfrac{5√((x^4)^2)~~ - ~~9}{√((x^4)^2 x)}\implies \cfrac{5x^4~~ - ~~9}{x^4√(x)}`
