Work: Calculate the value of equation 3.98×6.9/2+(7.2×(2×6.9-7.2/2)/16+7.2×(2×6.9-7.2/2)/16+7.2^2/16+7.2^2/16+(7.2×2-2.4)×2.4/8+(7.2×2-2.4)×2.4/8)×4.6 .
Question type: Mathematical calculation
Solution:
3.98×6.9/2+(7.2×(2×6.9-7.2/2)/16+7.2×(2×6.9-7.2/2)/16+7.2^2/16+7.2^2/16+(7.2×2-2.4)×2.4/8+(7.2×2-2.4)×2.4/8)×4.6
=3.98×6.9/2+(7.2×10.2/16+7.2×(2×6.9-7.2/2)/16+7.2^2/16+7.2^2/16+(7.2×2-2.4)×2.4/8+(7.2×2-2.4)×2.4/8)×4.6
=3.98×6.9/2+(7.2×10.2/16+7.2×10.2/16+7.2^2/16+7.2^2/16+(7.2×2-2.4)×2.4/8+(7.2×2-2.4)×2.4/8)×4.6
=3.98×6.9/2+(7.2×10.2/16+7.2×10.2/16+7.2^2/16+7.2^2/16+12×2.4/8+(7.2×2-2.4)×2.4/8)×4.6
=3.98×6.9/2+(7.2×10.2/16+7.2×10.2/16+7.2^2/16+7.2^2/16+12×2.4/8+12×2.4/8)×4.6
=3.98×6.9/2+22.86×4.6
=27.462/2+22.86×4.6
=13.731+22.86×4.6
=13.731+105.156
=118.887
Answer:3.98×6.9/2+(7.2×(2×6.9-7.2/2)/16+7.2×(2×6.9-7.2/2)/16+7.2^2/16+7.2^2/16+(7.2×2-2.4)×2.4/8+(7.2×2-2.4)×2.4/8)×4.6=118.887
