e2x=4
Is 2x an exponent? Use e^2x = 4 for exponents.
e^2x = 4
2x = ln(4)
x = ln(4)/2 = ln(2)
x =~ 0.693147

e%5E%282x%29=4

In order to "undo" the "e^", you must take the ln of each side of the equation:
ln%28e%5E%282x%29%29=+ln%284%29
2x=ln%284%29+

Finally, divide both sides by 2.
%282x%29%2F2=%28ln%284%29%29%2F2
x=+%28ln%284%29%29%2F2

This answer does NOT reduce!!

For additional help with LOGARITHMS and EXPONENTIAL FUNCTIONS, please see my own website by clicking on my tutor name "rapaljer" anywhere in algebra.com. Then click on my website. On my Homepage, look for the link "Basic, Intermediate, and College Algebra: One Step at a Time." Then choose "College Algebra", then "Chapter 4 (Logarithms)", and see Section 4.01. I have a complete explanation of Logarithms that I think you will find my explanation a lot easier to understand than traditional textbooks. Besides this, many of my exercises are solved IN COLOR in the MATH IN LIVING COLOR pages that go with this.

In addition to my written explanations of this topic, there is a video explanation from my own classes from before I retired. All of this is FREE if you have RealPlayer. If you don't have RealPlayer, then it is a FREE download.

I have many other topics from Basic, Intermediate, and College Algebra that are explained in detail, with many of these topics explained on video as well. Everything on the website is FREE.
