[1/1 Formula]
    Work: Calculate the value of equation 0.1×124.0×(0.45)^2+0.177×8.78×(0.45)^2 .
    Question type: Mathematical calculation
    Solution:
          0.1×124.0×(0.45)^2+0.177×8.78×(0.45)^2
        =0.1×124.0×0.45^2+0.177×8.78×(0.45)^2
        =0.1×124.0×0.45^2+0.177×8.78×0.45^2
        =0.1×124×0.2025+0.177×8.78×0.45^2
        =0.1×124×0.2025+0.177×8.78×0.2025
        =12.4×0.2025+0.177×8.78×0.2025
        =2.511+0.177×8.78×0.2025
        =2.511+1.55406×0.2025
        =2.511+0.314697
        =2.825697

    Answer:0.1×124.0×(0.45)^2+0.177×8.78×(0.45)^2=2.825697
