log9×log4

log9×log4log9×log4log9×log45log2

求证:log4 3*log4 5

求证:log43*log45求证:log43*log45求证:log43*log45log43*log45=log4*43*5=log1615

log4 3.6 和 log4 3.2那个大

log43.6和log43.2那个大log43.6和log43.2那个大log43.6和log43.2那个大第一个大呗前面的大前者

(1/4)^log4(3)

(1/4)^log4(3)(1/4)^log4(3)(1/4)^log4(3)(1/4)^log₄3=(1/4)^[(log‹1/4›3)/(log‹1

8^log4 7=

8^log47=8^log47=8^log47=楼主题目中的“log47”是“以4为底7的对数”的意思吧?如果是的话:8^(log47)=(2^3)^[(log27)/(log24)]=(2^3)^[
