You can put this solution on YOUR website!
2%5Ex%2B1=1%2F32

Please read my lesson---An overview to the laws of logarithms

2%5Ex%2B1-1=1%2F32-1
2%5Ex%2B0=-31%2F32
2%5Ex=-31%2F32
log%282%5Ex%29=log%28-31%2F32%29
xlog%282%29=log%28-31%29-log%2832%29

WAIT!!
log%28-31%29 is IMPOSSIBLE>

Thus, and therefore, there is no solution.:)
