Answer 2

take its derivative?

Answer 3

cant say i know what its taking about.

Answer 4

ln(4)

Answer 5

ln(4x) - ln(x) is yout thought?

Answer 6

i put it into my calculator and i got ln(4)

Answer 7

well the integration makes sense since 1/t ups to ln(t)

then evaluate it at the limits 4x to x

Answer 8

another way is to take the derivative:

d/dx F(x) = d/dx F(4x) - d/dx F(x)

d/dx F(x) = 4f(4x) - f(x)

since f=1/t

d/dx F(x) = 4/4x - 1/x

d/dx F(x) = 1/x - 1/x = 0 for all x between 0 adn inf

and since the derivative of a constant is 0, yada yada

Answer 9

other than that, im not sure what they want as proof

Answer 10

how to i evaluate it at 4x to x

Answer 11

to=do

Answer 12

plug it in like any other limit

Answer 13

can u show me im having a brain fart

Answer 14

im not going to do a basic integration problem for you

how do we do integration with limits?

Answer 15

never mine i figured it out. thanks for everything :)

Answer 16

k, good luck
