Work: Calculate the value of equation 4.1×(1.8+1.65)×2+3.1×(1.8+1.65)×2×9 .
Question type: Mathematical calculation
Solution:
4.1×(1.8+1.65)×2+3.1×(1.8+1.65)×2×9
=4.1×3.45×2+3.1×(1.8+1.65)×2×9
=4.1×3.45×2+3.1×3.45×2×9
=14.145×2+3.1×3.45×2×9
=28.29+3.1×3.45×2×9
=28.29+10.695×2×9
=28.29+21.39×9
=28.29+192.51
=220.8
Answer:4.1×(1.8+1.65)×2+3.1×(1.8+1.65)×2×9=220.8
