$= \log (x^3 + 1)^{1/3} + \log (x^2 + 1)^{1/2}$

$= \, ....$

3. ## What???

What exactly do you mean do here?

First I used the log rule $\log A^m = m \log A$ on each term to get what I posted.

Then I anticipated that you would use the log rule $\log A + \log B = \log (AB) \, .....$

5. ## ok

Understood. It is always best to use words in addition to calculations to help make things easier for students. Agree?
