Work: Calculate the value of equation 2.1×(18.84+0.3×2+0.67×2.1)×(63.06+0.3×2+0.67×2.1)+2.1×(7.48+0.3×2+0.67×2.1)×3+2.1×(7.18+0.3×2+0.67×2.1)×3 .
Question type: Mathematical calculation
Solution:
2.1×(18.84+0.3×2+0.67×2.1)×(63.06+0.3×2+0.67×2.1)+2.1×(7.48+0.3×2+0.67×2.1)×3+2.1×(7.18+0.3×2+0.67×2.1)×3
=2.1×20.847×(63.06+0.3×2+0.67×2.1)+2.1×(7.48+0.3×2+0.67×2.1)×3+2.1×(7.18+0.3×2+0.67×2.1)×3
=2.1×20.847×65.067+2.1×(7.48+0.3×2+0.67×2.1)×3+2.1×(7.18+0.3×2+0.67×2.1)×3
=2.1×20.847×65.067+2.1×9.487×3+2.1×(7.18+0.3×2+0.67×2.1)×3
=2.1×20.847×65.067+2.1×9.487×3+2.1×9.187×3
=43.7787×65.067+2.1×9.487×3+2.1×9.187×3
=2848.548673+2.1×9.487×3+2.1×9.187×3
=2848.548673+19.9227×3+2.1×9.187×3
=2848.548673+59.7681+2.1×9.187×3
=2848.548673+59.7681+19.2927×3
=2848.548673+59.7681+57.8781
=2908.316773+57.8781
=2966.194873
Answer:2.1×(18.84+0.3×2+0.67×2.1)×(63.06+0.3×2+0.67×2.1)+2.1×(7.48+0.3×2+0.67×2.1)×3+2.1×(7.18+0.3×2+0.67×2.1)×3=2966.194873
