Question

(1.09)^x=3

Answer 1

Hint: Take logs of both sides to get

x log(1.09) = log(3)

Answer 2

Can u elaborate more?

Answer 3

Do you know how to use the log function on your calculator?

Answer 4

no not a clue

Answer 5

can u just show me how to set the problem up?

Answer 6

I did show you how to set it up.

Answer 7

I'm still not understanding how to solve this.

Answer 8

So, @Hero described the mathematics of the problem, and I suggested that you use your calculator to compute log(1.09) and log(3) to get x. What are you not getting?

Answer 9

The basic principle here is that
log(a^b) = b log(a)
Have you studied that?

Answer 10

ok i found the log thing on my calculator. i did log(1.09) & got 0.03742649794.
Then i did log(3) & got 0.4771212547.
What now?

Answer 11

You have
0.03742649794 times x = 0.4771212547

Answer 12

ok i put that into mathway & got x=12.7482

Answer 13

THX 4 the help!!!!!
