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

lg5乘lg8000+(lg2^根号下3)^2/lg600-(1/2)lg0.036-(1/2)lg0.1
[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)/[lg(6/0.06) 2]
=3(lg5 lg2)/(lg100 2)
=3/(2 2)
=3/4
