57 x 76 + 13 x 57 + 11 x 57
= 57 x ( 76 + 11 + 13 )
= 57 x 100
= 5700
57 x 76 + 13 x 57 + 11 x 57
= 57 ( 76 + 13 + 11 )
= 57 x 100
= 5700
57x76+13x57+11x57

57 x 76 + 13 x 57 + 11 x 57
= 57 x ( 76 + 13 + 11 )
= 57 x 100
= 5700
= 57 x ( 76 + 13 + 11 ) =
57 x 100 = 5700
\(57.76+13.57+11.57\)
\(=57.\left(76+13+11\right)\)
\(=57.100=5700\)
Chúc bạn học tốt!
