Question 254778
The answer can't be 2.
{{{2^(2+5)=128}}}
{{{3^(2)=9}}}
.
.
.
Take the log (base 2) of both sides. 
Convert the right hand side to base 2. 
{{{log(2,3^(x))=log(3,3^(x))/log(3,2)}}}
The equation then becomes,
{{{x+5=x/(log(3,2))}}}
{{{x*(1-1/log(3,2))=5}}}
{{{x=5/(1-1/log(3,2))}}}
Approximately, the answer is 
{{{x=8.55}}}
{{{2^(8.55+5)=11993}}}
{{{3^(8.55)=12005}}}
