Logs
Solve to find possible values of n: log( (1+2n)^3 - 8n ) = log (1+2n) + log(4(1+n^2))
What's your point? You can't do it or you are just setting a Q for everyone to do? If it is that you have a question, where have you got to?
Probably, the first step is to use log law log a + log b = log ab on the RHS and then remove the logs. Then see where are which will be with a cubic polynomial equation.
