Work: Calculate the value of equation 700×20×(162.9-10)+2×20×(162.9-20)×(162.9-20)/2 .
Question type: Mathematical calculation
Solution:
700×20×(162.9-10)+2×20×(162.9-20)×(162.9-20)/2
=700×20×152.9+2×20×(162.9-20)×(162.9-20)/2
=700×20×152.9+2×20×142.9×(162.9-20)/2
=700×20×152.9+2×20×142.9×142.9/2
=14000×152.9+2×20×142.9×142.9/2
=2140600+2×20×142.9×142.9/2
=2140600+40×142.9×142.9/2
=2140600+5716×142.9/2
=2140600+816816.4/2
=2140600+408408.2
=2549008.2
Answer:700×20×(162.9-10)+2×20×(162.9-20)×(162.9-20)/2=2549008.2
