Question 133279
{{{27*(3^(3x+1)) = 3}}}
{{{3^(3x+1) = 1/9}}}
{{{3^(3x+1) = 1/(3^2)}}}
{{{3^(3x+1) = 3^(-2)}}}
{{{3x + 1 = -2}}}
{{{3x = -3}}}
{{{x = -1}}} answer
check answer:
{{{27*(3^(3x+1)) = 3}}}
{{{27*(3^(3*(-1)+1)) = 3}}}
{{{27*(3^(-2)) = 3}}}
{{{27 / (3^2) = 3}}}
{{{27/9 = 3}}}
{{{3 = 3}}}
OK
