Question 620725: If 9e^3t=27, then t=
My answer choices are:
A)27 B) Ln cubed root 3 C) 1 D)Ln 3 E) Ln 9
This is how I've been solving it:
9e^3t=27
e^3t=3 Divided by 9 on both sides
Lne^3t=Ln3 "Taking the ln on both sides"
(3t)Lne=Ln3 Power Property
3t(1)=Ln3 The natural log of e just so happens to be 1
3t=Ln3
t=Ln3/3 Divide by 3 on both sides
