Arent you suppose to find the anti-derivative of f'(x) = 2^(x) / x?

Mr F did not use any method ..

He get the answer by using the FTC ..

The problem here is that \(\displaystyle \int \frac{2^x}{x} \, dx\) is unelementary integral ..

What ever you do, you can not evaluate it in terms of elementary functions ..
