log5^6*log6^7*log*7^8*log8^9*log9*10*lg5=
log5^6×log6^7×log7^8×log8^9×log9^10等于多少?
若log3^5 log5^7 log7^x=log4^2 log6^4 log8^6,求x=?
log2(3)*log3(4)*log4(5)*log5(6)*log6(7)*log7(8)=?
log2(3)+log3(4)+log4(5)+log5(6)+log6(7)+log7(8)
(log4 3+log8 3)(log3 5+log9 5)(log5 2+log25 2)=
log2为底3*log3为底4*log4为底5log5底6*log6底7*log7底8=
7log8^9=a log3^5=b 求lg2 lg3 lg5
log3(4)×log4(8)×log8(x)=log6(36)
比较log6为底7的对数和log5为底6的对数的大小
1.log2 3*log3 4*log4 5*log5 2 2.(log4 3+log8 3)8(log3 2+log9
数学log的计算1.(lg5)^2+lg2*lg502.(log6^2)^2+log6^3*log6^2+log6^33
根号 [25^(1/lg5)] + [49^(1/log8 7)] 如图
