Własności logarytmów:
Prawa działań na logarytmach:
================================================================
A=(-∞, log₅75-log₅3)=(-∞, 2)
B=(log₃1/√3, 7>=(-1/2, 7>
--------------------------------------------------------
AuB=(-∞, 7>
AnB=(log₃1/√3, log₅75-log₅3) [=(-1/2, 2)]
A\B=(-∞, log₃1/√3> [=(-∞, -1/2>]
B\A=<log₅75-log₅3, 7> [-<2, 7>]
