## Homework Statement

Hi again

Practicing log differentiation now :P

Sorry for all the questions, i have a midterm on thursday and i need to get this stuff by then

1. e

^{x2}ln(2x+1)

2.ln(2x/(2x+1))

3. (3x-2)

^{x}(use logarithmic differentiation even though unnecessary

## The Attempt at a Solution

1. e

^{x2}ln(2x+1)

=>e

^{x2}*2x*(2/(2x+1))

is that right?

2. ln(2x/(2x+1))

=>ln(2x)-ln(2x+1)

=>2/(2x)-2(2x+1)

and is that one right? :)

3. (3x-2)

^{x}

f(x)=(3x-2)

^{x}

ln(y)=ln[((3x-2)

^{x}]

=>ln(y)=xln(3x-2)

=>1/y*y'=1*1/(3x-2)*3

=>1/y*y'=3/(3x-2)

=>y'=y(3/(3x-2)

=>y'=(3x-2)

^{x}(3/(3x-2)
