Question 172869
base of log in parenteses 
3Log(4) X = Log(4) 8
--------------
{{{3log(4,x) = log(4,8)}}}
{{{log(4,x^3) = log(4,8)}}}
{{{x^3 = 8}}}
{{{x^3 - 8 = 0}}}
{{{(x-2)*(x^2 + 2x + 4) = 0}}}
x = 2 (one answer)
The other 2 solutions are complex numbers.  The log of a complex number is outside the scope of this level.
