化简(0.027^2/3)^-1.5,
问题描述:
化简(0.027^2/3)^-1.5,
化简(0.027^2/3)^-1.5,
化简(x^2/3.y1/4.z^-1).(x^-1.y^3/4.z^3)^-1/3
答
解 ((0.027)^(2/3))^(-3/2)=0.027^(-1)
=(27/1000)^(-1)
=1000/27化简(x^2/3.y1/4.z^-1).(x^-1.y^3/4.z^3)^-1/3(x^2/3.y1/4.z^-1).(x^-1.y^3/4.z^3)^-1/3
=(x^2/3.y1/4.z^-1).(x^(1/3).y^(-1/4).z^(-1))
=xz^(-2)
=x/z^2
