[1/1 Formula]
    Work: Calculate the value of equation 0.3*(0.06-0.022)^2+0.5*(0.04-0.022)^2+0.2*(0.102)^2 .
    Question type: Mathematical calculation
    Solution:
          0.3*(0.06-0.022)^2+0.5*(0.04-0.022)^2+0.2*(0.102)^2
        =0.3*0.038^2+0.5*(0.04-0.022)^2+0.2*(0.102)^2
        =0.3*0.038^2+0.5*0.018^2+0.2*(0.102)^2
        =0.3*0.038^2+0.5*0.018^2+0.2*0.102^2
        =0.3*0.001444+0.5*0.018^2+0.2*0.102^2
        =0.3*0.001444+0.5*0.000324+0.2*0.102^2
        =0.3*0.001444+0.5*0.000324+0.2*0.010404
        =0.000433+0.5*0.000324+0.2*0.010404
        =0.000433+0.000162+0.2*0.010404
        =0.000433+0.000162+0.002081
        =0.000595+0.002081
        =0.002676

    Answer:0.3*(0.06-0.022)^2+0.5*(0.04-0.022)^2+0.2*(0.102)^2=0.002676
