-25 x 72 + 25 x 21 - 49 x 25
= 25 x (-72 + 21 - 49)
= 25 x (-100)
= -2500
-25 x 72 + 25 x 21 - 49 x 25
= 25 x ( -72 ) + 25 x 21 - 49 x 25
= 25 x ( -72 + 21 - 49 )
= 25 x ( - 100 )
= -2500
-25 x 72 + 25 x 21 - 49 x 25
= 25 x (-72 + 21 - 49)
= 25 x (-100)
= -2500
mik nah nhất đó
- 25 x 72 + 25 x 21 - 49 x 25
= 25 x ( - 72 ) + 25 x 21 - 49 x 25
= 25 x ( - 72 + 21 - 49 )
= 25 x ( - 100 )
= - 2500
K mk nha
-25×72+25×21-49×25=25×(-72+21-49)
=25×(-100)
=-2500
Nhớ k cho mk nhak bạn
- 25 x 72 + 25 x 21 - 49 x 25
= 25 x ( - 72 ) + 25 x 21 - 49 x 25
= 25 x ( - 72 + 21 - 49 )
= 25 x ( - 100 )
= - 2500
K mk nha
