Question 806846
{{{4log(x)-3log((x^2+1))+2 log(x-1)}}}
All these logs are base 10 we know this because logs base 10 dont need to show the 10 like log base 7 or log base 3 would.  It just shows log.
If there is a number before the log it is an exponent.
The above equation can be written 
{{{log(x^4)-log((x^2+1)^3)+log((x-1)^2)}}}
Now we will use the division/multiplication property..
{{{log(((x^4)(x-1)^2/((x^2+1)^3)))}}}
When there is a minus sign before the log it is on the bottom.  If there is a plus before the log it goes on top.
