Work: Calculate the value of equation 1/2×2050×(636.83)^2-1/2×(2050-300)×(636.83-242)^2 .
Question type: Mathematical calculation
Solution:
1/2×2050×(636.83)^2-1/2×(2050-300)×(636.83-242)^2
=1/2×2050×636.83^2-1/2×(2050-300)×(636.83-242)^2
=1/2×2050×636.83^2-1/2×1750×(636.83-242)^2
=1/2×2050×636.83^2-1/2×1750×394.83^2
=1/2×2050×405552.44890000007581-1/2×1750×394.83^2
=1/2×2050×405552.44890000007581-1/2×1750×155890.728899999987334
=0.5×2050×405552.44890000007581-1/2×1750×155890.728899999987334
=1025×405552.44890000007581-1/2×1750×155890.728899999987334

=415691260.1225-0.5×1750×155890.728899999987334
=415691260.1225-875×155890.728899999987334
=415691260.1225-136404387.7875
=279286872.335
Answer:1/2×2050×(636.83)^2-1/2×(2050-300)×(636.83-242)^2=279286872.335
