$x^{18}$, B. Subtract the exponents
Based on the quotient rule for exponents, we know that $\frac{a^{m}}{{a}^{n}}=a^{m-n}, a\ne0$ (where $m$ and $n$ are positive integers and $a$ is a real number). Therefore, we can simplify the given expression by subtracting the exponents. $\frac{x^{35}}{x^{17}}=x^{35-17}=x^{18}$
