Question

Solve the given exponential equation
e^2x-3=40

Answer 1

to cancel e
you have to take "ln" both side \[\huge\rm e^x \]
take ln to cancel e\[\ln e^x =x \]
ln and e cancel out so left is just x
(example)

Answer 2

\[\huge\rm \color{red}{ln} e^{2x-3} =\color{red}{\ln} 40\]
take ln to cancel out e
