log8^9/log2^3的值是log8^9/log2^3的值是log8^9/log2^3的值是log8(9)/log2(3)=(lg9/lg8)/(lg3/lg2)=[(2lg3)/(3lg2)]/
log8^9/log2^3的值是
log8^9/log2^3的值是
log8^9/log2^3的值是
log8(9)/log2(3)
=(lg9/lg8)/(lg3/lg2)
=[(2lg3)/(3lg2)]/(lg3/lg2)
=(2/3)(lg3/lg2)/(lg3/lg2)
=2/3
原式==(lg9/lg8)/(lg3/lg2)
=(2lg3/3lg2)/(lg3/lg2)
=2/3
log8^9=9log8=9log2^3
so log8^9/log2^3=9
log8^9/log2^3的值是
log8(9)*log2(3)
（log8 9） /（log2 3）的值.8和2是底数.
log8 9/log2 3的值是?重要是过程分析
(log8 9/log2 3)=?
求(log2^3+log8^9)
log8^9/log2^3 的值 卧草这底数都不同..怎么算?8和2是底数
log8的9次方/log2的3次方=
log2的三/log8的九的值是A3/2 B1 C2/3 D2
求(log2)^3+(log5)^3+log5×log8的值.
log8的27除以log2的3
求（log2^3+log8^9)(log3^4+log9^8+log3^2)的值
对数的平方如何算?log8^9=log2^3^3^2是怎么得来的?
( log8^9 )/( log2^3 )求值其中2和8是底数 3和9是真数
(log8 9/log2 3) =(lg9/lg8)/(lg3/lg2) ,这是为什么尼
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
