Algebra

Is this the second time you posted this?

I'm sorry I did intend to look at it before.  

Can you mark the other one as done please when you get this answer.

$$log(2x)+logx^2-log4\\\\ =log(2x\times x^2\div 4)$$

and you can finish it.     

$$log (9a) - Log (3a^{2}) + log 3 + log a\\ =log(9a\times 3a \div (3a^2))$$

and you can finish it
