oblicz: a)log₃15+log₃45-2log₃⁵ b)log₅6-3(log₅2+log₅3)/log₅6 pilne

a)log₃15+log₃45-2log₃⁵=log₃(15x45)-2log₃5=log₃675-log₃5²=log₃(675/25)=log₃27=3 b)log₅6-3(log₅2+log₅3)/log₅6=log₅6-3log₅6/log₅6=-2log₅6/log₅6=-2

a) log₃15 + log₃45 - 2log₃⁵ = log₂ (15*45) - log₃5² = = log₃(3*5*5*9/25) = = log₃(3*9*25/25) = = log₃27 = = 3 b) log₅6 - 3(log₅2 + log₅3)/log₅6 = log₅6 - 3log₅(2*3)/log₅6 = = log₅6 - 3log₅/log₅6 = = log₅6 - 3 = = log₅6 - log₅125 = = log₅6/125 lub jeśli : [log₅6 - 3(log₅2 + log₅3)]/log₅6 = [log₅6 - 3log₅(2*3)]/log₅6 = = (log₅6 - 3log₅6)/log₅6 = = - 2log₅6/log₅6 = = - 2
