Question 78841

When you see log (stuff multiplied together) and one of the things is a 2, it comes out as a log 2 + log of other stuff

The reason for a - is if you divided by something

If you divided by 5 then you subtract log 5

This should give you the answer

All the answers have the log(x^3) as 3 log x   correct.

You know that is not - because you didn't divide by x^3.
