890x10+890x0=0
952x5+952x5+952=10472
k mk nha
890 x 10 + 890 x 0
= 890 x ( 10 + 0 )
= 890 x 10
= 8900
952 x 5 + 952 x 5 + 952
= 952 x 5 + 952 x 5 + 952 x 1
= 952 x ( 5 + 5 + 1 )
= 952 x 11
= 10472
890*10+890*0
=8900+0
=8900
952*5+952*5+952
=952*(5+5)+952
=9520+952
=10472
890*(10+0)
=890*10
=8900
952*(5+5+1)
=952*11
=10472
890 x 10 + 890 x 0
= 890 x 10 + 0
= 8900 + 0
= 8900
\(890\times10+890\times0\)
\(=890\times\left(10+0\right)\)
\(=890\times10=8900\)
\(925\times5+925\times5+925\)
\(=952\times\left(5+5\right)+952\)
\(=952\times10+925\)
\(=9250+925\)
\(=10175\)
tíc mình nha
890x10+890x0
=890x(10+0)
=890x10
=8900
952x5+952x5+952
=952x(5+5+1)
=952x11
=10472
Chúc bạn học giỏi nha!!!
K cho mik vs nhé mọi người
952 x 5 + 952 x 5 + 952
= 952 x 5 + 952 x 5 + 952 x 1
= 952 x ( 5 + 5 + 1)
= 952 x 11
= 10472
890 x 10 + 890 x 0
= 890 x ( 10 + 0 )
= 890 x 10
= 8900
890 x 10 + 890 x 0
= 890 x ( 10 + 0 )
= 890 x 10
= 8900
952 x 5 + 952 x 5 + 952
= 952 x 5 + 952 x 5 + 952 x 1
= 952 x ( 5 + 5 + 1 )
= 952 x 11
= 10472
Ta có :
890 x 10 + 890 x 0
= 890 x ( 10 + 0 )
= 890 x 10
= 8900
