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

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

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

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

    it's ln 5 at left side not just 5

    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?

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

    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

    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.

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