Question

Find the 2nd derivative of (e^(2x)+7)/(3x)

Answer 1

use quotient rule

Answer 2

first we can begin by factoring out the 1/3, do you see that?

Answer 3

yep

Answer 4

now, we have to use the qutient rule on the remianing fraction

Answer 5

my 1st derivative would be (2xe^(2x)-e^(2x)-7) / (3x^(2))

Answer 6

um not quite

Answer 7

can you try and factor out the common facotrs in the numerator

Answer 8

oh and by the way, getting the 2nd derivative is going to be a very long process

Answer 9

do i multiply the top by 3 again to get the 2nd

Answer 10

you have to do the quotient rule on the 1st derivaitve
