log%280.5%29%2Flog%2825%29.....assuming the base is 10

=log%285%2F10%29%2Flog%285%5E2%29

=%28log%285%29-log%2810%29%29%2F2log%285%29

=%28log%285%29-log%282%2A5%29%29%2F2log%285%29

=%28log%285%29-%28log%282%29%2Blog%285%29%29%29%2F2log%285%29

=%28log%285%29-log%282%29-log%285%29%29%2F2log%285%29

=-log%282%29%2F2log%285%29 => exact solution

=-0.2153382790367=> approximate solution
