Question

Rewrite the expression
4logx−5log(x^2+1)+4log(x−1)
as a single logarithm logA.

Answer 1

i have an answer but im not sure if its correct ((x^4)/((x^2+1)^5(x-1)^4))

Answer 2

very close. the (x-1)^4 is positive so it should be in the numerator. otherwise, excellent :)

Answer 3

ok i thought it went with the bottom so it doesn't matter where the function is i just have to check for the signs right

Answer 4

right
