(log9(8))*(log4(3根号3))?
备注:3根号3是:3(上角标)根号下3.
备注:3根号3是:3(上角标)根号下3.
因为 (log9(8))=(3/2)(ln2 /ln3)
(log4(3根号3))=(1/3)(ln3 /ln2)
所以 (log9(8))*(log4(3根号3))=1/2
再问: 不对哦,这的是错误答案······
再答: 因为 (log9(8))=(3/2)(ln2 /ln3)
(log4(3根号3))=(1/6)(ln3 /ln2)
所以 (log9(8))*(log4(3根号3))=1/4
不好意思,第二步少了一个2
(log4(3根号3))=(1/3)(ln3 /ln2)
所以 (log9(8))*(log4(3根号3))=1/2

(log9(8))*(log4(3根号3))?
[log4(3)/log4(8)][log3(2)log9(2)]
计算log9(根号2)*[log4(3)+log8(3)]
log4(3)*log9(2)+log2(4倍根号下64) log9(32)*log64(2
(log4(3)+log8(3))(log3(2)+log9(2))-log4(3)×log1/3(四次根号32)
(1)log4 27乘以log25 8乘以log9 5 (2)(log4 3+log8 3)(log3 2+log9 2
2^(log4 (2-根号3))+3^(log9(2+根号3))=
(log2(3)+log4(9)+……+log2^n(3^n))·log9(n次根号8)=
计算(log2 3+log4 9+log8 27+……+log2^n 3^n)log9 n次根号3
(log3 2)+log9 2)*(log4 3+log8 3)+(log3 3^1/2)^2+ln根号e-lg1
log4(底数)8(真数)—log9分之1(底数)3(真数)等于多少
(log2 3+log4 27)*(log3 4+log9 8)=
