(log3 4+log3 8)(log2 3+log2 9)+(log3 根号2)(log9 7)/(log1/3 7)(log三次根号4 8)
(log3 4+log3 8)(log2 3+log2 9)+(log3 根号2)(log9 7)/(log1/3 7)(log三次根号4 8)
(log3 4+log3 8)(log2 3+log2 9)+(log3 根号2)(log9 7)/[(log1/3 7)(log三次根号4 8)]
=(5lg3 2)(3lg3 2)+[9(lg2 3)(lg3 7)/4]/[9(-lg3 7)]
=15 - (lg2 3)/4
log2^9*log3^8
(log2(3)+log8(9))x(log3(4)+log9(8)+log3(2))
求（log2^3+log8^9)(log3^4+log9^8+log3^2)的值
(log3 4+log3 8)(log2 3+log2 9)+(log3 根号2)(log9 7)/(log1/3 7)(log三次根号4 8)
