(log4 3+log8 3)(log3 5+log9 5)(log5 2+log25 2)=
(log2 3/log2 4+log2 3/log2 8)(log3 5/log3 3+log3 5/log3 9)(log5 2/log5 5+log5 2/log5 25)
=[(5log2 3)/6][(3log3 5)/2][(3log5 2)/2]
然后全部换成以2为底的对数得上式=（5/6)(3/2)(3/2)[(log2 3/log2 2)（log2 5/log2 3）(log2 2/log2 5)]=15/8
=[(5log2 3)/6][(3log3 5)/2][(3log5 2)/2]
然后全部换成以2为底的对数得上式=（5/6)(3/2)(3/2)[(log2 3/log2 2)（log2 5/log2 3）(log2 2/log2 5)]=15/8
(log4 3+log8 3)(log3 5+log9 5)(log5 2+log25 2)=
1.log2 3*log3 4*log4 5*log5 2 2.(log4 3+log8 3)8(log3 2+log9
(log4 3+log8 3)(log3 2+log9 2)-log1/2 32^1/3+5^(log25 9）
（1）log4 27乘以log25 8乘以log9 5 （2）（log4 3+log8 3）（log3 2+log9 2
log3(2)*log5(3)*log8(5)
化简(log4(3)+log8(3))(log3(2)+log9(2))
(log4^3+log8^3)(log3^2+log9^2)
求值(log4(3)+log8(3))×(log3(2)+log9(2))
求值(log3(2)+log9(2))*(log4(3)+log8(3))
(log3 2+log9 2)*(log4 3+log8 3)求值
(log3^2 + log9^4)×(log4^3 + log8^3)
求值:(log4^ 3+log8 ^9)*(log3^ 2+log9 ^16)
