Honestly dude, this helped a lot. I had 0 clue on how to do it. If only they had a 2nd function log base key like other Sharps. THanks

I followed step 3 correctly, but step 4 was incorrect when you said "In" instead of " log, "which is correct to get the same amount from step 3. In step 4, both answers are the same.
