Problema Solution
Rewrite the expression
(2 log x) - (5 log (x^2+1)) +(4 log (x-1))
as a single logarithm \log A. Then the function
A=
Answer provided by our tutors
(2 log x) - (5 log (x^2+1)) +(4 log (x-1)) =
= log x^2 - (log (x^2+1)^5 + log (x-1)^4) =
= log x^2 - log ((x^2+1)^5 (x-1)^4) =
= log x^2/((x^2+1)^5 (x-1)^4)
