A transistor is used in an amplifier circuit in common emitter mode. If the base current changes by $\displaystyle 100 \mu \mathrm{~A}$, it brings a change of $\displaystyle 10$ mA in collector current. If the load resistance is $\displaystyle 2 \mathrm{k} \Omega$ and input resistance is $\displaystyle 1 \mathrm{k} \Omega$, the value of power gain is $\displaystyle x \times 10^4$. The value of $\displaystyle x$ is
