Work: Calculate the value of equation 155×(4.688+3.688+4.088+3.488)+1/2×52.7×3.188×5.1+1/2×52.7×8.5×3.188 .
Question type: Mathematical calculation
Solution:
155×(4.688+3.688+4.088+3.488)+1/2×52.7×3.188×5.1+1/2×52.7×8.5×3.188
=155×15.952+1/2×52.7×3.188×5.1+1/2×52.7×8.5×3.188
=2472.56+1/2×52.7×3.188×5.1+1/2×52.7×8.5×3.188
=2472.56+0.5×52.7×3.188×5.1+1/2×52.7×8.5×3.188
=2472.56+26.35×3.188×5.1+1/2×52.7×8.5×3.188
=2472.56+84.0038×5.1+1/2×52.7×8.5×3.188
=2472.56+428.41938+1/2×52.7×8.5×3.188
=2472.56+428.41938+0.5×52.7×8.5×3.188
=2472.56+428.41938+26.35×8.5×3.188
=2472.56+428.41938+223.975×3.188
=2472.56+428.41938+714.0323
=2900.97938+714.0323
=3615.01168
Answer:155×(4.688+3.688+4.088+3.488)+1/2×52.7×3.188×5.1+1/2×52.7×8.5×3.188=3615.01168
