32 . 23 + 32 . 41 + 64 . 68
= 32 . 23 + 32 . 41 + 32 . 2 . 68
= 32 . 23 + 32 . 41 + 32 . 136
= 32 . ( 23 + 41 + 136 )
= 32 . 200
= 6400
# Học tốt #
32 . 23 + 32 . 41 + 64 . 68
= 32 .(23 + 41) + 64 . 68
= 32 . 64 + 64 . 68
= 64 . ( 32 + 68 )
= 64 . 100
= 6400
k mình nha.Hok tốt
32 . 23 + 32 . 41 + 64 . 68
= 32 . 23 + 32 . 41 + 32 . 2 . 68
= 32 . ( 23 + 41 + 68 ) . 2
= 32 . 132 .2
= ( 32 . 2 ) . 132
= 64 . 132
= 8448
=\(32\left(23+41+2.68\right)=32.200=6400\)
= 32.23+32.41+32.2+68
=32.(23+41+68*2)
=32.(23+41+136)
=32.200
=6400
32 . 23 + 32 . 41 + 64 . 68
= 32 . ( 23 + 41 ) + 64 . 68
= 32 . 64 + 64 . 68
= 64 . ( 32 + 68 )
= 64 . 100
= 6400
