Best ResponseYou've already chosen the best response.0write in single ln form product rule \[\large \rm ln x + \ln y = \ln ( x \times y )\]

Best ResponseYou've already chosen the best response.0Could you go on? because I'm still confused.

Best ResponseYou've already chosen the best response.0let's say x represent 5 and 2x represent y how would you condense ln in single ln form ? just like in this equation \[\large \rm ln x + \ln y = \ln ( x \times y )\]

Best ResponseYou've already chosen the best response.0Well it goes like ln(2x)=−5+5 ln(2x)=0 (e)0=2x e0=2x 1=2x 2x=1 x=1/2

Best ResponseYou've already chosen the best response.0alright first step is wrong why did you subtract 5 ?

Best ResponseYou've already chosen the best response.0it's ln 5 at left side not just 5

Best ResponseYou've already chosen the best response.0My 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 righthand 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?

Best ResponseYou've already chosen the best response.0alright nope you can't subtract 5 bec it's ln(5)

Best ResponseYou've already chosen the best response.0first 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
