How to calculate log without calculator??
Does it have a numerical value??

Just like e= 2.72

Thanks for the help!
 
No, logs require that you know the base and has no specific number like ln where the base is always e

For the PCAT, they'll only ask you questions where you can do it by hand like:

log2 8 = ? (Note: I'm too lazy to make that 2 a subscript🙂)

You should be able to do that without a calculator.

Remember, if you see something like log 100 = ?, then the default log base is 10 and the answer should be 2.
