Question

1)f(x)=2x^(4x)


2)f(x)=4^xlog(small 7)(x)


3)f(x)=[Inx]^4

4)f(x)=In(sqrt(6x+7)(7x-3))

5)f(x)=5cos(7In(x))

6(f(x)=x^2(x-7)^5/(x^2+6)^2

f(x)'=

Answer 1

Logarithmic Derivatives

Answer 2

@hartnn

Answer 3

so, you clear till here :
'left is 1/y
right is 4x(1/2x)+(In2x)(4)'

Answer 4

yes.

Answer 5

try this :
f'(x)=2x^(4x) *[2+4ln (2x)]

Answer 6

product rule?

Answer 7

you solved it already, i am just giving you a form you can enter...

Answer 8

thank you , i will try it

Answer 9

i entered it but it says wrong:/

Answer 10

simplified it to,
4x^(4x) *[1+2ln (2x)]
now ?

Answer 11

and last try, 4x^(4x) *[1+ln (4x^2)]

Answer 12

No :( i hate webwork

Answer 13

then,i don't think i can help you further on this...

Answer 14

thank you, i grealy apprecaite it
