hok tốt
a.38 + 41 + 117 + 159 + 62 = (38 + 62) + (41 + 159) + 117 = 100 + 200 + 117 = 300 + 117 = 417
b.341 x 67 + 659 x 83 + 341 x 16 = 341 x (16 + 67) + 659 x 83 = 341 x 83 + 659 x 83 = (341 + 659) x 83 = 1000 x 83 = 83000
a) 38 + 41 + 117 + 159 + 62 = ( 38 + 62 ) + ( 41 + 159 ) + 117 = 100 + 200 + 117 = 417

Chúc bạn học tốt!
341 x 67 + 341 x 16 + 659 x 83
= ( 67 +16 ) x 341 + 659 x 83
= 83 x 341 + 659 x 83
= 83 x ( 341 + 659 )
= 83 x 1000
= 83000
Đúng
341 . 67 + 341 . 16 + 659 . 83
= 341 . ( 67 + 16 ) + 659 . 83
= 341 . 83 + 659 . 83
= ( 341 + 659 ) x 83
= 1000 x 83
= 83000
