(log2 3+log8 9)(log3 4+log9 8+log3 2)的运算过程
关于换底公式的都懂不起哟
(log2 3+log8 9)(log3 4+log9 8+log3 2)的运算过程关于换底公式的都懂不起哟
注明一下
loga的n次方 b的m次方=(m/n)loga b
loga b=lg b/lg a
原式
=(log2 3+log8 9)(log3 4+log9 8+log3 2)
=[log2 3+(2/3)log2 3][2log3 2+(3/2)log3 2+log3 2]
=(5/3)log2 3*(9/2)log3 2
=(15/2)(lg 3/lg 2)(lg 2/lg 3)
=15/2
(log2 3+log8 9)(log3 4+log9 8+log3 2)
=(log2 3+log2^3 3^2)(log3 2^3+log3^2 2^3+log3 2)
=(log2 3+2/3log2 3)(3log3 2+3/2log3 2+log3 2)
=(5/3log2 3)*(11/2log3 2)
=55/6
(log2(3)+log8(9))x(log3(4)+log9(8)+log3(2))
求(log2^3+log8^9)(log3^4+log9^8+log3^2)的值
log8(9)*log2(3)
log3^36-log3^4+log2(log2^16)+8^2/3+(27/8)^-1/3+log8^27/log4^9怎么算啊,不好意思哦,我已经没分啦.麻烦一下写一写log2(log2^16) (27/8)^-1/3 log8^27/log4^9
(log8 9/log2 3)=?
求(log2^3+log8^9)
求值:(log4(3)+log8(3))(log3(2)+log3(4))-log2(64)
log3(2)*log8(9)
利用换底公式求值:1.log2 25 ×log3 4 ×log5 9 2.(log4 3+log8 3)(log3 2+log9 2)
(log2 3+log8 9)(log3 4+log9 8+log3 2)的运算过程关于换底公式的都懂不起哟
log8^9/log2^3的值是
求值:(log4^ 3+log8 ^9)*(log3^ 2+log9 ^16)
(log4^3+log8^3)(log3^2+log9^2)+log2^(32)的1/4次方
已知log2^3=a.则log8^3= log8^9=
求值:log8(底数)9/log2(底数)3 (过程)
log8的9次方/log2的3次方=
计算题:(log2的次方+log8 9的立方)(log3 4的立方+log9 8的立方+log3 2的立方)过程图图图图图图图图
