n * log ( a ) = log ( a ^ n )
log ( a ) + log ( b ) = log ( a * b )
log ( a ) - log ( b ) = log ( a / b )
2 log ( 3 ) = log ( 3 ^ 2 ) = log ( 9 )
2 log ( 2 ) = log ( 2 ^ 2 ) = log ( 4 )
2 log ( 3 ) - log ( 5 ) + 2 log ( 2 ) =
log ( 3 ^ 2 * 2 ^ 2 / 5 ) =
log ( 9 * 4 / 5 ) =
log ( 36 / 5 )
log ( a ) + log ( b ) = log ( a * b )
log ( a ) - log ( b ) = log ( a / b )
2 log ( 3 ) = log ( 3 ^ 2 ) = log ( 9 )
2 log ( 2 ) = log ( 2 ^ 2 ) = log ( 4 )
2 log ( 3 ) - log ( 5 ) + 2 log ( 2 ) =
log ( 3 ^ 2 * 2 ^ 2 / 5 ) =
log ( 9 * 4 / 5 ) =
log ( 36 / 5 )
