Question 153282
{{{17^(x+2)=3a^(x-1)}}}
{{{log (17^(x+2))=log (3a^(x+1))}}}
{{{(x+2)log 17=log 3 + log (a^(x+1))}}}
{{{(x+2)log 17=log 3 + (x+1)log a}}}
{{{x*log17+2log17=log3+x*log a+log a}}}
{{{x*log17-x*log a=log3+log a -2log17}}}
{{{x(log17-log a)=log3+log a -log17^2}}}
{{{x(log17-log a)=log3+log a -log289}}}
{{{x*log(17/a)=log(3a/289)}}}
{{{x=log(3a/289)/log(17/a)}}}
