计算(0.0081)^(-1/4)-10×0.027^(1/3)+lg(1/4)-lg25=?
计算(0.0081)^(-1/4)-10×0.027^(1/3)+lg(1/4)-lg25=?

计算(0.0081)^(-1/4)-10×0.027^(1/3)+lg(1/4)-lg25=?
(0.0081)^(-1/4)-10×0.027^(1/3)+lg(1/4)-lg25=[(3/10)^4](-1/4)-10*(0.3)^3*1/3+lg1/4/25=10/310*0.3+lg1/100=10/3-3+(-2)=-5/3

(0.0081)^(-1/4)=10/3
10×0.027^(1/3)=10*0.3=3
lg(1/4)-lg25=lg(1/100)=-2lg(10)=-2
10/3-3-2=-5/3
