    y(prime)=1/x(e^x)+e^x(In) and my answer is y(prime)=e^x(1/x+In)

    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

    one question, is it possible to cancel well when rewritten.....ln=1/w so we have 1/x e^x is it possible to cancel out the x's?

    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
