(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

(log3 4+log3 8)(log2 3+log2 9)+(log3 根号2)(log9 7)/(log1/3 7) (log2(3)+log8(9))x(log3(4)+log9(8)+log3(2)) (log2 3+log8 9)(log3 4+log9 8+log3 2)的运算过程 [log2(3)+log4(9)][log3(4)+log9(2)]等于 (log3^4+log5^2)(log2^9+log2^根号3) log2(3)=a,log3(7)=b.log12(56)=log3(7*8)=log3(7)+3log3(2) log2 3×log3 7=log2 7 log2(3)+log3(5)+log3(2)=? (log3,4+log9,4)log4,3—log2,2根号2 这怎么解答了 1.log2 3*log3 4*log4 5*log5 2 2.(log4 3+log8 3)8(log3 2+log9 log2^3*log3^7*log7^8 (log2^3 +log3^5) x ( log3^5 +log9^5 ) x lg 2 ,
