We can get a solution by changing the exponential equation to log form.
Take natural log of both sides of the equation.
In(e^x) = In(2)
The left side becomes x because the natural log of e^x is just x.
We now have this:
x = In(2)
Use calculator to find x.
x = 0.693
NOTE: I also want to add that the decimal number 0.6931471806 can be rounded off to three decimal places. This is why I selected the approximate value for x = 0.693
Is this clear?
