Work: Calculate the value of equation (2.1-0.02×2)×(2.85-0.02×2)×2+(2.1-0.02×2)×(1.95-0.02×2)×4+(1.55-0.02×2)×(3.45-0.02×2)×2 .
Question type: Mathematical calculation
Solution:
(2.1-0.02×2)×(2.85-0.02×2)×2+(2.1-0.02×2)×(1.95-0.02×2)×4+(1.55-0.02×2)×(3.45-0.02×2)×2
=2.06×(2.85-0.02×2)×2+(2.1-0.02×2)×(1.95-0.02×2)×4+(1.55-0.02×2)×(3.45-0.02×2)×2
=2.06×2.81×2+(2.1-0.02×2)×(1.95-0.02×2)×4+(1.55-0.02×2)×(3.45-0.02×2)×2
=2.06×2.81×2+2.06×(1.95-0.02×2)×4+(1.55-0.02×2)×(3.45-0.02×2)×2
=2.06×2.81×2+2.06×1.91×4+(1.55-0.02×2)×(3.45-0.02×2)×2
=2.06×2.81×2+2.06×1.91×4+1.51×(3.45-0.02×2)×2
=2.06×2.81×2+2.06×1.91×4+1.51×3.41×2
=5.7886×2+2.06×1.91×4+1.51×3.41×2
=11.5772+2.06×1.91×4+1.51×3.41×2
=11.5772+3.9346×4+1.51×3.41×2
=11.5772+15.7384+1.51×3.41×2
=11.5772+15.7384+5.1491×2
=11.5772+15.7384+10.2982
=27.3156+10.2982
=37.6138
Answer:(2.1-0.02×2)×(2.85-0.02×2)×2+(2.1-0.02×2)×(1.95-0.02×2)×4+(1.55-0.02×2)×(3.45-0.02×2)×2=37.6138
