Logaritmu īpašības

Izmantojot pakāpju īpašības, iespējams pamatot logaritmu īpašības, kuras izmanto, lai pārveidotu izteiksmes, kas satur logaritmus:

1. logc a + logc b = logc ab
2. logc a - logc b = logc

3. logc ab = b · logc a

Piemērs

log627 - log63 + 2log62 =
= log6(27:3) +2log62 =
= log69 + log622 =
= log69 + log64 =
= log6(9 · 4) =
= log636 =
= 2
