press ln function in your calculator
type in 6.5 or 3/8
you will get the answer
ln(6.5)=1.871802177
that is also equal to log of 6.5 to the base 2.717281828
ln(3/8)=-0.980829253
that is also equal to log of 3/8 to the base 2.717281828

ln (6.5) and ln(3/8)?
The simple factor of the matter is that you can't; not without a calculator. You'd have to plug in the value on a scientific calculator and your approximation would be right there. There are no pen and paper ways to solve it.
There are ways it can get modified, though.
ln(6.5) = ln(65/10) = ln(65) - ln(10)
ln(3/8) = ln(3) - ln(8)
But that doesn't contribute to finding the value.

First display the number 6.5 by pressing the buttons 6, . , and 5.
Then press the button marked ‘ln’ if it is in your calculator.
It will display the value.
Find the value of 3/8 as usual.
Once the value 0.375 is displayed in the screen, press the button ln to find ln of 3/8.
