# Anti-ln?!?!

posted by .

use a calculator to find the
anti-ln(-0.049)
to the nearest ten thousandth.
My calculator doesn't do anti-ln. just ln. Someone helo me please?

• Anti-ln?!?! -

Use the inverse key

INV LN (-.049)

or do this use the e^ key

anti-ln(a)= e^a

• Anti-ln?!?! -

Is the answer 0.9521811297? That's what I got using the e^ key.

(I don't have an inverse key on my calculator. It's a Casio fx-9750G PLUS Power Graphic, and the manual for it is literally one inch thick with 453 pages.)

• Anti-ln?!?! -

correct.

e^-.049=
