Work: Calculate the value of equation 1.3×((0.3+0.2+0.16+3)×0.9×0.9+(24+1.5)×1.0×0.9×0.9)+1.5×((2.5+2.0)×0.9×0.9+1.35) .
Question type: Mathematical calculation
Solution:
1.3×((0.3+0.2+0.16+3)×0.9×0.9+(24+1.5)×1.0×0.9×0.9)+1.5×((2.5+2.0)×0.9×0.9+1.35)
=1.3×(3.66×0.9×0.9+(24+1.5)×1.0×0.9×0.9)+1.5×((2.5+2.0)×0.9×0.9+1.35)
=1.3×(3.66×0.9×0.9+25.5×1.0×0.9×0.9)+1.5×((2.5+2.0)×0.9×0.9+1.35)
=1.3×23.6196+1.5×((2.5+2.0)×0.9×0.9+1.35)
=1.3×23.6196+1.5×(4.5×0.9×0.9+1.35)
=1.3×23.6196+1.5×4.995
=30.70548+1.5×4.995
=30.70548+7.4925
=38.19798
Answer:1.3×((0.3+0.2+0.16+3)×0.9×0.9+(24+1.5)×1.0×0.9×0.9)+1.5×((2.5+2.0)×0.9×0.9+1.35)=38.19798
