32 x 47 + 32 x 52 + 32 = 32 x (47 + 52 + 1)
= 32 x 100
= 3200
32 x 47 + 32 x 52 + 32
= 32 x 47 + 32 x 52 + 32 x 1
= 32 x ( 47 + 52 + 1 )
= 32 x 100
= 3200
32 x 47 + 32 x 52 + 32
= 32 x 47 + 32 x 52 + 32 x 1
= 32 x (47+52+1)
= 32 x 100
= 3200
k cho mk nha 
nguyễn thanh huyền
32 x 47 + 32 x 52 + 32
= 32 x 47 + 32 x 52 + 32 x 1
= 32 x ( 47 + 52 + 1 )
= 32 x 100
= 3200
32x47+32x52+32
=32x(47+52+1)
=32x100
=3200
32 x 47 + 32 x 52 + 32
= 32 x 47 + 32 x 52 + 32 x 1
= 32 x ( 47 + 52 + 1 )
= 32 x 100
= 3 200
Vậy 32 x 47 + 32 x 52 + 32 = 3 200
= 32 x 47 + 32 x 52 + 32 x 1
= 32 x [ 47 + 52 + 1 ]
= 32 x 100
= 3200
k mình mình k lại
32 x 47 + 32 x 52 + 32
=32 x47 +32 x 52 + 32 x 1
= 32 x (47 + 52 +1)
=32 x 100
