write in single ln form product rule $\large \rm ln x + \ln y = \ln ( x \times y )$

2. anonymous

Could you go on? because I'm still confused.

3. Nnesha

let's say x represent 5 and 2x represent y how would you condense ln in single ln form ? just like in this equation $\large \rm ln x + \ln y = \ln ( x \times y )$

4. anonymous

I keep getting 1/2

5. Nnesha

$\large \rm ln x + \ln y = \ln ( x \times y )$ $\large\rm ln 5 + \ln (2x) = ?$

6. Nnesha

show your work how did you get 1/2 ?

7. anonymous

Well it goes like ln(2x)=−5+5 ln(2x)=0 (e)0=2x e0=2x 1=2x 2x=1 x=1/2

8. Nnesha

alright first step is wrong why did you subtract 5 ?

9. Nnesha

it's ln 5 at left side not just 5

10. anonymous

My choices are 1.1484 2.11.17 3.71.71 4.0.02 also since Since 5 does not contain the variable to solve for, we move it to the right-hand side of the equation by subtracting 5 from both sides. If I'm wrong can you direct me in the direction of the right answer by showing me how to do it?

11. Nnesha

alright nope you can't subtract 5 bec it's ln(5)

12. anonymous

Okay, well can you show me, please ?

13. Nnesha

first of all apply product property $\large \rm ln x + \ln y = \ln ( x \times y )$ $\large\rm ln 5 + \ln (2x) = ln(5 \times2x)$ there is a plus sign so you have to apply product property

14. Nnesha

$\huge\rm ln (5 \times 2x) =5$ now take e both side do it let me know what yo uget

Wait I did something wrong

17. Nnesha

yes try again :-)

18. anonymous

Sorry, I'm not sure what to do. I'm pretty brain dead because I have been working on my math final since like 7 am.

19. Nnesha

math final ?

20. Nnesha

is it from a test ?? :-)

21. anonymous

Mhm, I have about 16 questions left out of 50.

22. Nnesha

sorry...

I didn't feel like it was cheating, I was just asking for explanation rather than the answer, you know?

27. anonymous

Well I'll close the question, I wasn't aware, sorry.
