Question 979726
<pre>
{{{expr(3/2)(ln(x^2+1)^""-ln(x+1)-ln(x-1))}}}

Factor a -1 out of the last two natural logs

{{{expr(3/2)(ln(x^2+1)^""-(ln(x+1)^""+ln(x-1)))}}}

Write the sum of logs as the log of a product:

{{{expr(3/2)(ln(x^2+1)^""-ln((x+1)^""(x-1)))}}}

Write the difference of logs as the log of a quotient:

{{{expr(3/2)ln((x^2+1)/((x+1)^""(x-1)))}}}

Finally we write the coefficient of the log as an exponent
of what the log is taken of

{{{ln((x^2+1)/((x+1)^""(x-1)))^(3/2)}}}
