    作业：求算式 (2.1-0.433)^2*(-0.28-0.0933)^2+(0.2-0.433)^2*(0.08-0.0933)^2+(-1-0.433)^2*(0.48-0.0933)^2 的值.
    题型：数学计算
    解:
          (2.1-0.433)^2*(-0.28-0.0933)^2+(0.2-0.433)^2*(0.08-0.0933)^2+(-1-0.433)^2*(0.48-0.0933)^2
        =1.667^2*(-0.28-0.0933)^2+(0.2-0.433)^2*(0.08-0.0933)^2+(-1-0.433)^2*(0.48-0.0933)^2
        =1.667^2*(-0.3733)^2+(0.2-0.433)^2*(0.08-0.0933)^2+(-1-0.433)^2*(0.48-0.0933)^2
        =1.667^2*(-0.3733)^2+(-0.233)^2*(0.08-0.0933)^2+(-1-0.433)^2*(0.48-0.0933)^2
        =1.667^2*(-0.3733)^2+(-0.233)^2*(-0.0133)^2+(-1-0.433)^2*(0.48-0.0933)^2
        =1.667^2*(-0.3733)^2+(-0.233)^2*(-0.0133)^2+(-1.433)^2*(0.48-0.0933)^2
        =1.667^2*(-0.3733)^2+(-0.233)^2*(-0.0133)^2+(-1.433)^2*0.3867^2
        =2.778889*-0.3733^2+(-0.233)^2*(-0.0133)^2+(-1.433)^2*0.3867^2
        =2.778889*0.13935289+(-0.233)^2*(-0.0133)^2+(-1.433)^2*0.3867^2
        =2.778889*0.13935289+0.054289*(-0.0133)^2+(-1.433)^2*0.3867^2
        =2.778889*0.13935289+0.054289*0.00017689+(-1.433)^2*0.3867^2
        =2.778889*0.13935289+0.054289*0.00017689+2.053489*0.3867^2
        =2.778889*0.13935289+0.054289*0.00017689+2.053489*0.14953689
        =0.387246+0.054289*0.00017689+2.053489*0.14953689
        =0.387246+0.00001+2.053489*0.14953689
        =0.387246+0.00001+0.307072
        =0.387256+0.307072
        =0.694328
    答案:(2.1-0.433)^2*(-0.28-0.0933)^2+(0.2-0.433)^2*(0.08-0.0933)^2+(-1-0.433)^2*(0.48-0.0933)^2=0.694328
