OpenStudy (anonymous):
is that 3^(x-2) or 3^x - 2?
OpenStudy (anonymous):
not sure I understand the difference... It's to the power of X-2... does that help?
OpenStudy (anonymous):
okay that helps
OpenStudy (anonymous):
so you get 3^x-2 = 3. If you log base 3 both sides, you get x-2 = 1. Solve fore x to get x=3
OpenStudy (anonymous):
awesome thank you! That makes sense... I just wasn't sure if I should log both sides or not, and couldn't remember! Thank you!!!
