[1/1 Formula]
    Work: Calculate the value of equation 0.1×138.93×(0.15)^2+0.177×9.75×(0.15)^2 .
    Question type: Mathematical calculation
    Solution:
          0.1×138.93×(0.15)^2+0.177×9.75×(0.15)^2
        =0.1×138.93×0.15^2+0.177×9.75×(0.15)^2
        =0.1×138.93×0.15^2+0.177×9.75×0.15^2
        =0.1×138.93×0.0225+0.177×9.75×0.15^2
        =0.1×138.93×0.0225+0.177×9.75×0.0225
        =13.893×0.0225+0.177×9.75×0.0225
        =0.312592+0.177×9.75×0.0225
        =0.312592+1.72575×0.0225
        =0.312592+0.038829
        =0.351421

    Answer:0.1×138.93×(0.15)^2+0.177×9.75×(0.15)^2=0.351421
