1.	7. Prove that logb a + logc b x loga c = 1 , where x--> Multiply
Answer» tion:Let loga M = X ⇒ a sup>x = Mand Ioga N= y ⇒ AY = NNow ax ∙ ay = MN or, ax + y = MNTherefore from DEFINITION, we have,loga (MN) = x + y = loga M + loga N [PUTTING the values of x and y]Corollary: The law is true for more than two positive factors i.e.,loga (MNP) = loga M + loga N + loga Psince, loga (MNP) = 1oga (MN) + loga P = loga M+ loga N+ loga PTherefore in general, loga (MNP ….... )= loga M + loga N + loga P + ……. .plzzzz MARK me brainlist
