## swiftskier96 Group Title Help!?!?!?!? 17. Solve 1n 2 + 1n x = 5. Round to the nearest thousandth, if necessary. one year ago one year ago

1. swiftskier96 Group Title

I tried to put it in on my calculator, but it doesnt work. Either that, or i dont know how to do it.

2. artix_17 Group Title

How did u do it?

3. swiftskier96 Group Title

I used an online calculator. I typed the whole thing in like it says above, and it says that its unknown.

4. artix_17 Group Title

okay so first you have to group the terms together. Unknown on the left and known values on the right. ln x = 5 - ln 2

5. swiftskier96 Group Title

Ok.

6. artix_17 Group Title

So ln x = \[\log_{e} x\]

7. artix_17 Group Title

To find x, you need to move the log base over to the other side Therefore x = e^(5-ln 2)

8. swiftskier96 Group Title

Oh ok. That makes sence.

9. artix_17 Group Title

You can simplify 5-ln 2 further using calculator

10. Yahoo! Group Title

\[\log_{}a + \log b = \log (ab) \]

11. Yahoo! Group Title

\[\log_{e} 2x = 5\]

I got 4.3068528194400546905827678785418. (But ill obviously have to shorten it. :)

13. swiftskier96 Group Title

So it would be x = e^4.3?

14. artix_17 Group Title

Yes :)

15. swiftskier96 Group Title

So is that my final answer? Or do i have to solve more of it?

16. artix_17 Group Title

though its more accurate to leave it as 5-ln 2, that's your final answer

17. swiftskier96 Group Title

Oh ok. Cool! Thanks!!

18. artix_17 Group Title

No prob
