376 x 29 + 70 x 376 + 376
= 376 x 29 + 70 x 376 + 376 x 1
= 376 x (29 + 70 + 1)
= 376 x 100
= 37600
Sửa đề:
376 × 29 + 70 × 376 + 376
= 376 × (29 + 70 + 1)
= 376 × 100
= 37600
376 x 29 + 70 x 376 + 376
= 376 x 29 + 70 x 376 + 376 x 1
= 376 x (29 + 70 + 1)
= 376 x 100

57 \(\times\) 46 + 57 \(\times\) 54
= 57 \(\times\) ( 46 + 54)
= 57 \(\times\) 100
= 5700
137 + 355 + 63 + 45
= ( 137 + 63) + ( 355 + 45)
= 200 + 400
= 600
215 \(\times\) 48 - 215 \(\times\) 38

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 * 54 + ( 188 * 2 ) * 3 + 376 * 43
376 * 54 + 376 * 3 + 376 * 43
376 * ( 54 + 3 + 43 )
