$7\mathrm{.}43$ For the amplifier designed in Exercise $7\mathrm{.}41$ and analyzed in Exercise $7\mathrm{.}42,$ we want to raise $R_{in}$ to $10k.$ What is the required value of $R_e,$ and what does the overall voltage gain $G_v$ become?

Ans. $R_e=67\mathrm{.}2$;$G_v=-40\frac{V}{V}$

This is the figure below
