I think you meant CUBE root, not SQUARE root, so use "root(3,5-x)" not sqrt.



That's the log of a quotient, so we use 



Those are both logs of products, so we use  on the first log:



Now we must be careful to put a big parentheses around the second log's
break-up since it's preceded by a minus:



Now we can remove that big parentheses by changing the signs of the terms
inside the big parentheses:



Now we write the cube root as the 1/3 power:



Now we use  and also log(10) = 1:
