How does one calculate antilogarithms on this calulator? I've tried several different methods/sequences, and thus far none have worked. I need an answer ASAP since I have to calculate anitlogs during an upcoming exam. Help!!

Can you do it like this?

If this is the problem:

ln x = 2

Exponentiate both sides.

eln x = e2             ...and eln x = x

x = e2

x ≈ 7.389

Or if it is like this:

log10 x = 2

Exponentaite both sides:

10log x = 102

x = 102

x = 100

If the problem is really involved this might not be so easy...!

If you have the log value (base 10), to find the antilog, use the (10x) key.

Example:  if you have  log(x) = 0.3010,

using the (10x) key:  100.3010  =  2 (approximately).
