lne^x = xlne = x So y = x Now derivative it.

see ur que was to diff y= lne^x now as i said ln and exp cancels out each other so lne^x=x ie y=x dx/dx=1

you can do that way too but rem tis log n exponential r mirrors function dats y can cancel them out and wat micahwood50 says is also correct

micahwood50 Group TitleBest ResponseYou've already chosen the best response.1
Well, so y = x. Now derivative it.
