Work: Calculate the value of equation (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)×2+((7.2×2-2.4)×2.4/8+(7.2×2-2.4)×2.4/8)×2 .
Question type: Mathematical calculation
Solution:
(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)×2+((7.2×2-2.4)×2.4/8+(7.2×2-2.4)×2.4/8)×2
=(7.2×10.2/16+7.2×(2×6.9-7.2/2)/16+7.2^2/16+7.2^2/16)×2+((7.2×2-2.4)×2.4/8+(7.2×2-2.4)×2.4/8)×2
=(7.2×10.2/16+7.2×10.2/16+7.2^2/16+7.2^2/16)×2+((7.2×2-2.4)×2.4/8+(7.2×2-2.4)×2.4/8)×2
=15.66×2+((7.2×2-2.4)×2.4/8+(7.2×2-2.4)×2.4/8)×2
=15.66×2+(12×2.4/8+(7.2×2-2.4)×2.4/8)×2
=15.66×2+(12×2.4/8+12×2.4/8)×2
=15.66×2+7.2×2
=31.32+7.2×2
=31.32+14.4
=45.72
Answer:(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)×2+((7.2×2-2.4)×2.4/8+(7.2×2-2.4)×2.4/8)×2=45.72
