(log4-3+log8-3)(log3-2+log9-2)
补充说明一下,log4-3就是以4为底3的对数
一定一定要写清楚过程!
(log4-3+log8-3)(log3-2+log9-2)补充说明一下,log4-3就是以4为底3的对数一定一定要写清楚过程!
(log4-3+log8-3)(log3-2+log9-2)
=(1/2log2-3+1/3*log2-3)(log3-2 +1/2*log3-2)
=5/6*log2-3 * 3/2log3-2
=5/4
算错了,不好意思
(log4(3)+log8(3))*log3(2)
(log3^2 + log9^4)×(log4^3 + log8^3)
(log3 2+log9 2)*(log4 3+log8 3)求值
化简(log4(3)+log8(3))(log3(2)+log9(2))
求值:(log4^ 3+log8 ^9)*(log3^ 2+log9 ^16)
(log4(3)+log8(3))*(log3(2)+log8(2))-log1/2(^4√32)=?..
(log4(3)+log8(3))(log3(2)+log9(2))-log4(3)×log1/3(四次根号32)
求值:(log4(3)+log8(3))(log3(2)+log3(4))-log2(64)
急 求 (log3 2+log9 2)-(log4 3+log8 3)求 (log3 2+log9 2)-(log4 3+log8 3)
[log4(3)+log8(3)]*log3(2)答案是1/3么
求(log3^2 + log9^2)×(log4^3 + log8^3)的值.请给出过程,谢谢!
求值(log3(2)+log9(2))*(log4(3)+log8(3))打括号是真数.
【(log4)^3+.(log8)^3】【.(log3)^2+.(log9)^2】=几啊
(log4^3+log8^3)(log3^2+log9^2)详细计算过程.~
化简此式(log4 3+log8 3)×(log3 2+log9 2)
(log4 3+log8 3)(log3 5+log9 5)(log5 2+log25 2)=
计算:1 (log4 3+log8 3)log3 2 2 loga b×logb c×logc a
log3 4×log4 8×log8 a=log根号3 9,则a=
