gửi kb cho tớ nhé
35*50+35*49+35
=35*50+35*49+35*1
=35*(50+49+1)
=35*100
=3500
Tk nha
=35x50+35x{49+1}
=35x50+35x50
=35x{50+50}
=35x100
=3500
35 x 50 + 35 x 49 + 35
=35 x (50+49+1)
=3500
35 x 50 + 35 x 49 + 35
= 35 x 50 + 35 x 49 + 35 x 1
= 35 x ( 50 + 49 + 1 )
= 35 x 100
= 350
35 x 50 = 50 x 35
35 x 49 + 35 = 50 x 35
35 x ( 50 + 50 ) =3500
35 x 50 + 35 x 49 + 35 = 35 x ( 50 + 49 + 1 )
= 35 x 100
= 3500
đúng chứ
35x50+35x49+35=35x50+35x49+35x1
=35x(49+50+1)
=35x100
=3500
35.50+35.49+35
=35.50+35.49+35.1
=35.(50+49+1)
=35.100
=3500
k nha lm thế cho dễ hiểu !!!
35 x 50 + 35 x 49 + 35
= 35 x 50 + 35 x 49 + 35 x 1
= 35 x ( 50 + 49 + 1 )
= 35 x 100
= 3500
35*50+35*49+35
=35*50+35*49+35*1
=35*(50+49+1)
=35*100
=3500
