Final Answer :
D
Explanation :
Using the property $\sqrt{\frac{a}{b}}=\frac{\sqrt{a}}{\sqrt{b}}$ and simplifying under the square root sign we get: x18121y2=x18121y2=x911y\sqrt{\frac{x^{18}}{121y^2}}=\frac{\sqrt{x^{18}}}{\sqrt{121y^2}}=\frac{x^9}{11y}121y2x18=121y2x18=11yx9 Therefore, the answer is (D).
