Question 61501
 {{{log(2,(x+2)) + log(2,(x-2)) = 5}}}
{{{log(2, (x+2)(x-2)) = 5}}}
{{{log(2,(x^2-4)) = 5}}}
{{{2^5 = x^2 -4}}}
{{{32 = x^2 -4}}}
{{{x^2 = 36}}}
{{{x = +6}}}
{{{x = -6}}}
--------------------
{{{log(5)= 2-log(x)}}}
{{{log(5) + log(x) = 2}}}
{{{log(5x) = 2}}}
{{{10^2 = 5x}}}
{{{100 = 5x}}}
{{{x = 20}}}
--------------------
{{{ln(x)+ ln(x+2)= ln(8)}}}
{{{ln(x)+ ln(x+2) - ln(8) = 0}}}
{{{ln(x*(x+2) / 8) = 0}}}
{{{e^0 = (x)(x+2) / 8}}}
{{{1 =  (x)(x+2) / 8}}}
{{{(x)(x+2) = 8}}}
{{{x^2 + 2x - 8 = 0}}}
{{{(x+4)(x-2) = 0}}}
{{{x = -4}}}
{{{x = +2}}}
-------------------
{{{ln(x) - ln(x+1) = ln(x+3) - ln(x+5)}}}
{{{ln(x/(x+1)) = ln((x+3)/(x+5))}}}
{{{x /(x+1) = (x+3)/(x+5)}}}
{{{x^2 + 5x = x^2 + 4x + 3}}}
{{{x = 3}}}
