You can put this solution on YOUR website!
let x=log%285%2C4%29
Then we obtain
5%5Ex=4
log%2810%2C5%5Ex%29=log%2810%2C4%29
x%2Alog%285%29=log%284%29
x=log%284%29%2Flog%285%29
log%285%2C4%29=log%284%29%2Flog%285%29
The same way
log%289%2C37%29=log%2837%29%2Flog%289%29
Generally
log%28a%2Cb%29=logb%2Floga
