Question 323102
{{{2*log(2,x) + log(2,3) = log(2,27)}}}
{{{log(2,x^2) + log(2,3) = log(2,3^3)}}}
{{{log(2,x^2) = 3*log(2,3) - log(2,3)}}}
{{{log(2,x^2) = 2*log(2,3)}}}
{{{log(2,x^2) = log(2,3^2)}}}
{{{x^2 = 3^2}}}
{{{x^2 = 9}}}
{{{x = 3}}}
{{{x = -3}}} This must be discarded, since no log with a positive base can
give a negative result
I'll check for {{{x = 3}}}
{{{2*log(2,x) + log(2,3) = log(2,27)}}}
{{{2*log(2,3) + log(2,3) = log(2,27)}}}
{{{log(2,3^2) + log(2,3) = log(2,3^3)}}}
{{{log(2,3^3) = log(2,3^3)}}}
OK
