计算[(lg2+2lg3)/(2+lg0.9+lg0.2)]^3-4^6×2^(-13)
[(lg2+2lg3)/(2+lg0.9+lg0.2)]^3-4^6×2^(-13)
=[(lg2*9)/(2+lg0.9*0.2)]^3-4^6×2^(-13)
=[(lg18)/(lg100+lg0.9*0.2)]^3-4^6×2^(-13)
=[(lg18)/(lg18]^3-4^6×2^(-13)
=1-4^6×2^(-13)
=1-2^12×2^(-13)
=1-2^(-1)
=1/2
=[(lg2*9)/(2+lg0.9*0.2)]^3-4^6×2^(-13)
=[(lg18)/(lg100+lg0.9*0.2)]^3-4^6×2^(-13)
=[(lg18)/(lg18]^3-4^6×2^(-13)
=1-4^6×2^(-13)
=1-2^12×2^(-13)
=1-2^(-1)
=1/2
