3log%28%28+a%29%29%2B+5log%28%28a%29%29+-+6log%28%28a%29%29+=log%28%2864%29%29,
find a
log%28%28+a%5E3%29%29%2B+log%28%28a%5E5%29%29+-+log%28%28a%5E6%29%29+=log%28%2864%29%29
log%28%28+a%5E3%2Aa%5E5%29%29+-+log%28%28a%5E6%29%29+=log%28%2864%29%29
log%28%28+a%5E8%29%29+-+log%28%28a%5E6%29%29+=log%28%2864%29%29
log%28%28+a%5E8%2Fa%5E6%29%29+=log%28%2864%29%29
log%28%28+a%5E%288-6%29%29%29+=log%28%2864%29%29
log%28%28+a%5E2%29%29+=log%28%2864%29%29....if log same, then
a%5E2+=64
a+=sqrt%2864%29
a+=8
