which type of calculator do you have?

If you have   scientific calculator then  first press the shift key  then press the  e key  that will give the  base e means lne 

and for base 10 it will come directly. There will be a key  for log 10 on the calculator  .

IF you will not able to do  then please  send me the pic of calculator  I will tell  exactly .. because each calculator have different functions.

 Regarding any doubt plz let me know ... I will be happy to help you.

for base e you just press the Ln key  and then No which do you want to calculate 

for example  Find the values of Ln(20)

first press the Ln key then type 23 and then press enter key .

for same thing Log(20) means base 10

first press the log key then type 20 and then enter key 


I hope It will be helpful for you ...Any doubt you may ask the questions directly to me.
