Question

log[4](5x+2)-log[4](x-2)=2
How to solve this log ??
I know that log[a](x)=c => a^c=x but does that mean for this problem 4^2-4^2= (5x+2)(x-2)

Answer 1

subtraction of logs is division of their arguments

Answer 2

log4(a) = 2 ; therefore 4^2 = a

and your a = (5x+2)/(x-2)

Answer 3

logn - logm = log n/m

Answer 4

s would it be 4^2=(5x+2)/(x-2) ?

Answer 5

yes

Answer 6

there

Answer 7

the rest is just algebra

undivide, collect your xs, undistribute, and divide off the excess

Answer 8

Ooh. Okk. Thank you! And thanks for the drawing!

Answer 9
