Gravitation: JEE Main 2023 Physics question

If earth has a mass nine times and radius twice to that of a planet P. Then $\frac{v_{e}}{3} \sqrt{x} \mathrm{~ms}^{-1}$ will be the minimum velocity required by a rocket to pull out of gravitational force of $\mathrm{P}$, where $v_{e}$ is escape velocity on earth. The value of $x$ is
