2log5(25)-3log2(64)=?
5^log5(2)-4^log2(3)+3^log27(8)等于多少?
log2 5乘log5 4等于多少
log2 25乘log3 4乘log5 9等于多少 不用计算器
(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
有关log的数学题①log2(2X+3)=0②log5(X)-1/3log5(8)=0③log2(X)+log4(X)=
log2(5)*log5(8)化简
我是这样做的log2(3)*log3(5)*log5(49)*log7(64)=log2(3)*log3(5)*2log
[log2 (125) +log4(25)+log8(5)][log125(8)+log25(4)+log5(2)]
[log2 (125) +log4(25)+log8(5)][log125(8)+log25(4)+log5(2)
