Question 1155245
<br>
You're practically there...!<br>
{{{2+log((sqrt(1+x)))+3log((sqrt(1-x))) = log((sqrt(1-x^2)))}}}<br>
You saw the sqrt(1+x) and sqrt(1-x) on the left so you worked on the right:<br>
{{{2+log((sqrt(1+x)))+3log((sqrt(1-x))) = log((sqrt(1-x)))+log(sqrt(1+x)))}}}<br>
Cancel the like terms on the two sides and work with what is left.  It will be an easy equation to solve if you have a basic understanding of logarithms.<br>
