# 4e^(2x)+16=36solve equation for x and round answer to two decimal places. my steps so far: (if you could, please tell me where did I go wrong?) 4e^(2x)+16=36 e^(2x)+4=9 e^(2x)=5 ???????

e^(2x)=5

Now take ln in both sides.

ln(e^(2x)) = ln5

2xln(e) = ln 5

We know that ln(e) =1

Therefore;

2x = ln5

x= (ln5 )/2

**Using calculator x=0.80**
