lg5乘lg8000+(lg2^根号下3)^2/lg600-(1/2)lg0.036-(1/2)lg0.1

问题描述:

lg5乘lg8000+(lg2^根号下3)^2/lg600-(1/2)lg0.036-(1/2)lg0.1

请适当加点括号,免得产生歧义。

[lg5*lg8000 (lg2^根三)^2]/(lg600-1/2lg0.036-1/2lg0.1)=[(lg5*(lg8 3) (√3*lg2)^2]/[lg6 2-1/2lg(0.036*0.1)]=[3lg5*lg2 3lg5 3*(lg2)^2]/[lg6 2-lg√(0.0036)]=[3lg2(lg5 lg2) 3lg5]/[lg6 2-lg0.06]=(3lg2 3lg5)...
