1. ## Exponential equations.

The goal of the problem is to solve for x using logs and the given equation is this:

2e^(3x) = 4e^(5x)

Any help on how to solve this?

I'll start you off;

$2e^{3x}=4e^{5x}$

$e^{3x}=2e^{5x}$

$ln(e^{3x})=ln(2e^{5x})$

$3x=ln(2)+ln(e^{5x})$

Can you take it from here?

Keep in mind the handy rules $log_{a}a=1$, and $log_{a}b^c=c \cdot log_{a}b$

Yes, I was able to solve it from there.

Thank you! :]
