Question

Please help me answer this

Answer 1

Answer:

$\frac{8}{x3y}$

Here you go.Hope this help!!

Answer 2

$\\ \rm\hookrightarrow \dfrac{8x^4y^3}{x^7y^4}$

• a^m/a^n=a^m-n

$\\ \rm\hookrightarrow \dfrac{8x^{4-7}y^{3-4}}{}$

$\\ \rm\hookrightarrow 8x^{-3}y^{-1}$

$\\ \rm\hookrightarrow \dfrac{8}{x^3y}$
