求值:(log4(3)+log8(3))(log3(2)+log3(4))-log2(64)求值:(log4(3)+log8(3))(log3(2)+log3(4))-log2(64)求值:(log4
求值:(log4(3)+log8(3))(log3(2)+log3(4))-log2(64)
求值:(log4(3)+log8(3))(log3(2)+log3(4))-log2(64)
求值:(log4(3)+log8(3))(log3(2)+log3(4))-log2(64)
换底公式
原式=(lg3/lg4+lg3/lg8)(lg2/lg3+lg4/lg3)-log2(2^6)
=(lg3/2lg2+lg3/3lg2)(lg2/lg3+2lg2/lg3)-log2(2^6)
=[(1/2+1/3)(lg3/lg2)][(1+2)(lg2/lg3)]-6log2(2)
约分
=(1/2+1/3)(1+2)-6
=5/2-6
=-7/2
1/2log2(3) 1/3log2(3))(log3(2) log3(4))-6log2(2)=5/2log2(3)log3(2)-6=5/2-6=-7/2
(log3 2+log9 2)*(log4 3+log8 3)求值
求值:(log4^ 3+log8 ^9)*(log3^ 2+log9 ^16)
求值:(log4(3)+log8(3))(log3(2)+log3(4))-log2(64)
求值(log3(2)+log9(2))*(log4(3)+log8(3))打括号是真数.
log4(3)+log8(3) 怎么算
log4(3)+log8(3) 怎么相加?
(log4(3)+log8(3))*log3(2)
log4(3)-log4(12)-log8(4) =log4(3/12)- log8( 8^(2/3) ) log8( 8^(2/3) )怎么得出来的?
(log3^2 + log9^4)×(log4^3 + log8^3)
计算log9(根号2)*[log4(3)+log8(3)]
化简(log4(3)+log8(3))(log3(2)+log9(2))
计算:(log4 3+log8 3)×log9 √2=?
(log4(3)+log8(3))*(log3(2)+log8(2))-log1/2(^4√32)=?..
求值.(log3^2+log9^3)*(log4^3+log8^3)+(log3^3^1/2)^2+ln根号下e-lg1我实在是算不好了,要命啊急滴,
求值:【log2(3)+log4(9)+log8(27)+log16(81)+log32(243)】—5log2(3/2)
利用换底公式求值:1.log2 25 ×log3 4 ×log5 9 2.(log4 3+log8 3)(log3 2+log9 2)
(log4(3)+log8(3))(log3(2)+log9(2))-log4(3)×log1/3(四次根号32)
急 求 (log3 2+log9 2)-(log4 3+log8 3)求 (log3 2+log9 2)-(log4 3+log8 3)
