Work: Calculate the value of equation 2×2.69×8.03×2.5+1×3×8.03×2.5+1×3×27.95×2.5+2×3×53.38×2.5 .
Question type: Mathematical calculation
Solution:
2×2.69×8.03×2.5+1×3×8.03×2.5+1×3×27.95×2.5+2×3×53.38×2.5
=5.38×8.03×2.5+1×3×8.03×2.5+1×3×27.95×2.5+2×3×53.38×2.5
=43.2014×2.5+1×3×8.03×2.5+1×3×27.95×2.5+2×3×53.38×2.5
=108.0035+1×3×8.03×2.5+1×3×27.95×2.5+2×3×53.38×2.5
=108.0035+3×8.03×2.5+1×3×27.95×2.5+2×3×53.38×2.5
=108.0035+24.09×2.5+1×3×27.95×2.5+2×3×53.38×2.5
=108.0035+60.225+1×3×27.95×2.5+2×3×53.38×2.5
=108.0035+60.225+3×27.95×2.5+2×3×53.38×2.5
=108.0035+60.225+83.85×2.5+2×3×53.38×2.5
=108.0035+60.225+209.625+2×3×53.38×2.5
=108.0035+60.225+209.625+6×53.38×2.5
=108.0035+60.225+209.625+320.28×2.5
=108.0035+60.225+209.625+800.7
=168.2285+209.625+800.7
=377.8535+800.7
=1178.5535
Answer:2×2.69×8.03×2.5+1×3×8.03×2.5+1×3×27.95×2.5+2×3×53.38×2.5=1178.5535
