2log5^25–3log2^64等于?
2log5(25)-3log2(64)=?
log2/log5等于多少
(log3^4+log5^2)(log2^9+log2^根号3)
log的计算 :log2(20)-log4(25)= log3(2)×log2(5)×log5(3)=?log2[log
5^log5(2)-4^log2(3)+3^log27(8)等于多少?
我是这样做的log2(3)*log3(5)*log5(49)*log7(64)=log2(3)*log3(5)*2log
log2 5乘log5 4等于多少
log2^25*log3^2倍根号2*log5^9=
log2 25乘log3 4乘log5 9等于多少 不用计算器
log2 25*log3 4 *log5 9
利用换底公式求值:1.log2 25 ×log3 4 ×log5 9 2.(log4 3+log8 3)(log3 2+
数学(log5 √2*log7 9)/(log5 1/3 *log7 3√4)+log2( √(3+√5)- log√(
