Work: Calculate the value of equation 440×18×(170.8-9)+2×10×(542-389.2)×(542-389.2)/2 .
Question type: Mathematical calculation
Solution:
440×18×(170.8-9)+2×10×(542-389.2)×(542-389.2)/2
=440×18×161.8+2×10×(542-389.2)×(542-389.2)/2
=440×18×161.8+2×10×152.8×(542-389.2)/2
=440×18×161.8+2×10×152.8×152.8/2
=7920×161.8+2×10×152.8×152.8/2
=1281456+2×10×152.8×152.8/2
=1281456+20×152.8×152.8/2
=1281456+3056×152.8/2
=1281456+466956.8/2
=1281456+233478.4
=1514934.4
Answer:440×18×(170.8-9)+2×10×(542-389.2)×(542-389.2)/2=1514934.4
