Work: Calculate the value of equation 155×(2.188+1.988+1.788+1.588)+1/2×52.7×1.488×1.7+1/2×52.7×11.9×1.488 .
Question type: Mathematical calculation
Solution:
155×(2.188+1.988+1.788+1.588)+1/2×52.7×1.488×1.7+1/2×52.7×11.9×1.488
=155×7.552+1/2×52.7×1.488×1.7+1/2×52.7×11.9×1.488
=1170.56+1/2×52.7×1.488×1.7+1/2×52.7×11.9×1.488
=1170.56+0.5×52.7×1.488×1.7+1/2×52.7×11.9×1.488
=1170.56+26.35×1.488×1.7+1/2×52.7×11.9×1.488
=1170.56+39.2088×1.7+1/2×52.7×11.9×1.488
=1170.56+66.65496+1/2×52.7×11.9×1.488
=1170.56+66.65496+0.5×52.7×11.9×1.488
=1170.56+66.65496+26.35×11.9×1.488
=1170.56+66.65496+313.565×1.488
=1170.56+66.65496+466.58472
=1237.21496+466.58472
=1703.79968
Answer:155×(2.188+1.988+1.788+1.588)+1/2×52.7×1.488×1.7+1/2×52.7×11.9×1.488=1703.79968
