Question 726561
It is very hard to make these complicated expressions display the way we would write them on paper, but I will try.
{{{(1/5)log(2,z)+3log(2,y)-log(2,x)=log(2,(z^(1/5)))+log(2,(y^3))-log(2,y)=highlight(log(2,(z^(1/5)y^3/x)))=highlight(log(2,(z^0.2y^3/x)))=highlight(log(2,(root(5,z)y^3/x)))}}} 
The final answer displays funny in the first of the 3 versions, but you probably get the idea)
