Question 930350
to be  written in Sum or Difference form, you should be given this:

{{{ln(((x-4)^2)^(2/3)/(x^2-1)^(2/3)))}}}, then you have


{{{ln((((x-4)^2)/(x^2-1))^(2/3)))}}}


{{{(2/3)ln((((x-4)^2)/(x^2-1))))}}}


{{{(2/3)(ln((x-4)^2))-ln((x^2-1))))}}}


{{{(2/3)(2*ln(x-4)-ln((x-1)(x+1))))}}}

{{{(2/3)(2*ln(x-4)-(ln(x-1)+ln(x+1)))}}}


{{{(2/3)(2*ln(x-4)-ln(x-1)-ln(x+1))}}}
