$$\int{f}\left({x}\right){dx}={f}\left({x}\right) \\ $$$$\Rightarrow{f}\left({x}\right)={e}^{{x}} \\ $$$$\int\left({f}\left({x}\right)\right)^{\mathrm{2}} {dx}=\int{e}^{\mathrm{2}{x}} {dx}=\frac{{e}^{\mathrm{2}{x}} }{\mathrm{2}}+{C}=\frac{\left({f}\left({x}\right)\right)^{\mathrm{2}} }{\mathrm{2}}+{C} \\ $$
