base of log in parenteses
3Log(4) X = Log(4) 8
--------------
3log%284%2Cx%29+=+log%284%2C8%29
log%284%2Cx%5E3%29+=+log%284%2C8%29
x%5E3+=+8
x%5E3+-+8+=+0
%28x-2%29%2A%28x%5E2+%2B+2x+%2B+4%29+=+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.
