Work: Calculate the value of equation 0.7×0.12×172+0.7×0.24×181+0.9×0.24×208+1.2×0.24×20+1.8×0.24×64 .
Question type: Mathematical calculation
Solution:
0.7×0.12×172+0.7×0.24×181+0.9×0.24×208+1.2×0.24×20+1.8×0.24×64
=0.084×172+0.7×0.24×181+0.9×0.24×208+1.2×0.24×20+1.8×0.24×64
=14.448+0.7×0.24×181+0.9×0.24×208+1.2×0.24×20+1.8×0.24×64
=14.448+0.168×181+0.9×0.24×208+1.2×0.24×20+1.8×0.24×64
=14.448+30.408+0.9×0.24×208+1.2×0.24×20+1.8×0.24×64
=14.448+30.408+0.216×208+1.2×0.24×20+1.8×0.24×64
=14.448+30.408+44.928+1.2×0.24×20+1.8×0.24×64
=14.448+30.408+44.928+0.288×20+1.8×0.24×64
=14.448+30.408+44.928+5.76+1.8×0.24×64
=14.448+30.408+44.928+5.76+0.432×64
=14.448+30.408+44.928+5.76+27.648
=44.856+44.928+5.76+27.648
=89.784+5.76+27.648
=95.544+27.648
=123.192
Answer:0.7×0.12×172+0.7×0.24×181+0.9×0.24×208+1.2×0.24×20+1.8×0.24×64=123.192
