求(log2幂数3 +log4幂数3)(log3幂数2 +log9幂数4)

[log2(3)+log4(9)][log3(4)+log9(2)]等于 1.log2 3*log3 4*log4 5*log5 2 2.(log4 3+log8 3)8(log3 2+log9 若log2^3×log3^4×log4^x=log9^3 ,求x (log4^3+log8^3)*(log3^2+log9^2)-log2^4次√32 (log3,4+log9,4)log4,3—log2,2根号2 这怎么解答了 比较两个数的大小：log2*3和log3*4 (log3^2 + log9^4)×(log4^3 + log8^3) (log4＾3+log8＾3)(log3＾2+log9＾2)+log2＾(32)的1/4次方 （log2 3+log4 27）*（log3 4+log9 8）= (log3 4+log3 8)(log2 3+log2 9)+(log3 根号2)(log9 7)/(log1/3 7) [log4(3)/log4(8)][log3(2)log9(2)] 比较下列各数的大小:2^0.7,log5(4),log1/3(5),log3(1/4),log4(1/3),
