\(9876\cdot27+9876\cdot33+9876+40+9876\)
=\(9876\cdot\left(27+33+40\right)\)
=\(9876\cdot100\)
\(987600\)

2024 x 89 + 12 x 2024 - 2024
= 2024 x 89 + 12 x 2024 - 2024 x 1
= 2024 x (89 + 12 - 1)
= 2024 x 100
= 202400
2024 x 89 + 12 x 2024 - 2024
= 2024 x 89 + 12 x 2024 - 2024 x 1
= 2024 x (89 + 12 - 1)
= 2024 x 100
= 202400

376 x 54 + 188 x 3 x 2 + 376 x 43
= 376 x 54 + (188 x 2) x 3 +376 x 43
= 376 x 54 + 376 x 3 + 376 x 43
= 376 x (54 + 3 + 43)
= 376 x 100
= 37600
376 * 54 + ( 188 * 2 ) * 3 + 376 * 43
376 * 54 + 376 * 3 + 376 * 43
376 * ( 54 + 3 + 43 )
376 * 100
37600 mình nha
