You can put this solution on YOUR website!
1. log%2881%2C9%29=log%2881%2Csqrt%2881%29%29=log%2881%2C%2881%5E0.5%29%29=0.5

2. Maybe what is meant is
log%288%2C128%29=7%2F3<-->8%5E%227%2F3%22=128
128=2%2A64=2%2A8%5E2=2%2A%282%5E3%29%5E2=2%2A2%5E6=2%5E7 so 8%5E%227%2F3%22=8%5E%28%22%281%2F3%29%22%2A7%29=%288%5E%221%2F3%22%29%5E7=2%5E7
