〖1/1算式〗
    作业：求算式 (0.78+2.243*(1.5^0.5))*(1-0.3)*((0.993+0.18*0.3)-1.06*0.09+1.71*(0.3^3)) 的值.
    题型：数学计算
    解:
          (0.78+2.243*(1.5^0.5))*(1-0.3)*((0.993+0.18*0.3)-1.06*0.09+1.71*(0.3^3))
        =(0.78+2.243*1.224744871391589)*(1-0.3)*((0.993+0.18*0.3)-1.06*0.09+1.71*(0.3^3))
        =3.527103*(1-0.3)*((0.993+0.18*0.3)-1.06*0.09+1.71*(0.3^3))
        =3.527103*0.7*((0.993+0.18*0.3)-1.06*0.09+1.71*(0.3^3))
        =3.527103*0.7*(1.047-1.06*0.09+1.71*(0.3^3))
        =3.527103*0.7*(1.047-1.06*0.09+1.71*0.027)
        =3.527103*0.7*0.99777
        =2.468972*0.99777
        =2.463466
    答案:(0.78+2.243*(1.5^0.5))*(1-0.3)*((0.993+0.18*0.3)-1.06*0.09+1.71*(0.3^3))=2.463466
