Question

Natural Logs:
Can you help me figure out:
5ln(3x)+2=7?? THANKS!

Answer 1

First, subtract 2 from both sides.

Answer 2

ok so 5ln (3x)=5

Answer 3

not sure how do to the rest though? Is 3x raised to the power of 5?

Answer 4

Right, now divide both sides by 5 to get ln(3x) on its own.

Answer 5

so ln(3x)=1?

Answer 6

right. does that ring a bell? :D

Answer 7

oh ok, I get it now it's been a little while since I did these. Makes sense, I wasn't sure if you had to raise it to the power of 5? Must have been looking at the wrong example! THANK YOU!

Answer 8

What do you get for \(x\), just to confirm?

Answer 9

x=0.906

Answer 10

yes, or \(e/3\)

Answer 11

great thanks!

Answer 12

no problem!
