Question

find dy/ dx and simplify : y=lnx/e^(2x) ?

Answer 1

dy/dx= (1_2xlnx)/xe^(2x)

Answer 2

or you can write it : dy/dx=(1/xe^(2x)) _2y

Answer 3

i am confused , what exactly I have to do in this problem..

Answer 4

use quotient rule:\[\large \frac{\frac{e^{2x}}{x} + 2\ln x (e^{2x})}{e^{4x}}\]

Answer 5

that's supposed to be minus not plus

Answer 6

ok, thanks! I just didn't knew which rule to apply

Answer 7

QUOTIENT RULE \[\frac{ldh - hdl}{l^2}\] where l = low; h = high; d = derivative
