(log23+log49+.+以2的n次方为底3的n次方的对数)乘以log98的n次方根(log23+log49+.+以2的n次方为底3的n次方的对数)乘以log98的n次方根(log23+log49
(log2 3+log4 9+.+以2的n次方为底3的n次方的对数)乘以log9 8的n次方根
(log2 3+log4 9+.+以2的n次方为底3的n次方的对数)乘以log9 8的n次方根
(log2 3+log4 9+.+以2的n次方为底3的n次方的对数)乘以log9 8的n次方根
log(2^n)(3^n)=n/nlog2 3=log2 3
log(9) 8^(1/n)=1/n*log9 8
原式
=(log2 3+log2 3+...+log2 3)*1/n*log9 8
=nlog2 3*1/n*log9 8
=lg3/lg2*lg8/lg9
=lg3/lg2*3lg2/(2lg3)
=3/2
2^(2log2的3次方+log4的16次方 )
[log2(3)+log4(9)][log3(4)+log9(2)]等于注意:log2的2是下标,后同
(log2 3+log4 9+.+以2的n次方为底3的n次方的对数)乘以log9 8的n次方根
log2(12)-log4(9)的值是
算式log2^12-log4^9的值
比较log2(2/3)与log4(4/3) 注:log2的“2下标的
log2(20)-log2(5)+2log3(2)×log4(3)
log的计算 :log2(20)-log4(25)= log3(2)×log2(5)×log5(3)=?log2[log2(32)-log2(3÷4)+log2log的计算 :log2(20)-log4(25)= log3(2)×log2(5)×log5(3)=?log2【log2(32)-log2(3÷4)+log2(6)】=?lgx+lg(x+15)=2 ..X
log2(3)=a,log4(12),log6(9),以2为底3的对数是a,求以4为底12的对数,以6为底9的对数,用a表示
求x的值 log4^x=-2/3 log2^(log5^x)=0log4^x=-2/3 log2^(log5^x)=0 分开的
log2^x=log4^9
2log2为什么等于log4
化简:(log2(3)+log4(9)+log8(27)+…+log2n(3^n))*log2(8的n次方根)
(log2 3+log4 9+log8 27+...+log2^n 3^n)log9 32的N次方根
(log2 3+log4 9+log8 27+...+log2^n 3^n)log9 32的N次方根
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
(log2 3+log4 27)*(log3 4+log9 8)=log2的2是下标,后同
log2的12-log4的9 的值是多少?
