Best ResponseYou've already chosen the best response.0\[e^{9a} + 2e^{3a}  3e^{a} = 300\] Let \(e^a=y\) \[y^9+2y^33y=300\] \[y^9=300+3y2y^3\] \[ln(y)^9=ln(300+3y2y^3)\] \[9ln(y)=ln(300+3y2y^3)\] \[ln(y)=\frac{1}{9}ln(300+3y2y^3)\] \[ln(e^a)=\frac{1}{9}ln(300+3e^a2e^{3a})\] \[a=\frac{1}{9}\ln(300+3e^a2e^{3a})\]

Best ResponseYou've already chosen the best response.0This is the proving solution, I don't think you can solve for 'a' all at one side.
