log2^9*log3^8

(log3 4+log3 8)(log2 3+log2 9)+(log3 根号2)(log9 7)/(log1/3 7) 、计算:log2的9次方乘以log3的8次方 (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 9乘以log3 4等于多少 log2 25*log3 4 *log5 9 log2^3*log3^7*log7^8 (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) (-27/8)^3+(2-根号三)^0-1/9*log2^9*log3^4等于多少 log3（底数）8（真数）乘log2（底数）9（真数）等于多少? 利用对数的换地公式,计算log2 1/25*log3 1/8*log5 1/9
