Answer
x
Work Step by Step
We are given the expression $\frac{x^{9}y^{6}}{x^{8}y{6}}$.
We can simplify this expression by using the quotient rule, which holds that $\frac{a^{m}}{a^{n}}=a^{m-n}$ (where a is a nonzero real number, and m and n are integers).
$\frac{x^{9}y^{6}}{x^{8}y{6}}=(x^{9-8})\times (y^{6-6})=x\times y^{0}=x\times1=x$
