log4為底3 log以4為底8的對(duì)數(shù)？
log以4為底8的對(duì)數(shù)？等于1.5，對(duì)數(shù)基8與4的對(duì)數(shù)等于對(duì)數(shù)基8與log2的對(duì)數(shù)除以對(duì)數(shù)基4與log2的對(duì)數(shù)。以8為底的log2的對(duì)數(shù)等于3以4為底的log2的對(duì)數(shù)等于2因此為1.5。
log以4為底8的對(duì)數(shù)？
等于1.5，對(duì)數(shù)基8與4的對(duì)數(shù)等于對(duì)數(shù)基8與log2的對(duì)數(shù)除以對(duì)數(shù)基4與log2的對(duì)數(shù)。
以8為底的log2的對(duì)數(shù)等于3
以4為底的log2的對(duì)數(shù)等于2
因此為1.5。
