I keep getting 10/7 as an aswer but that isn't even one of the multiple choice!
Any help would be greatly appreciated!
Thanks in advance!
You will need these log properties
$\displaystyle \log(xy)=\log(x)+\log(y)$ and
$\displaystyle \log\left( \frac{x}{y}\right)=\log(x)-\log(y)$
$\displaystyle \log(x^c)=c\log(x)$
$\displaystyle \log_{a}(a)=1$
So you have
$\displaystyle \log_{a}\left(\frac{x^2 a}{y} \right)=\log_{a}(x^2a)-\log_{a}(y)=$
$\displaystyle \log_{a}(x^2)+\log_{a}(a)-\log_{a}(y) = 2\log_{a}(x)+\log_{a}(a)-\log_{a}(y)$
I hope this helps
