=23.(-63)+23.21-58.23
=23(-63+21-58)
=23.(-100)
=-2300
\(\left[\left(-23\right)+23-23\right]\cdot63+21-58\)
\(-23+26\)
\(3\)
=23.(-63)+23.21-58.23
=23.[(-63)+21-58]
=23.(-100)
=-2300
-23.63+23.21-58.23=-63.23+23.21-58.23=23.(-63+21-58)=23.(-100)=-2300
-23 . 63 + 23 . 21 - 58 . 23
=23 . (-63) + 23 . 21 - 58 . 23
=23 . ( -63 + 21 - 58 )
=23 . (-100)
=-2300
Ta có : -23. 63 +23. 21- 58 .23
=23.(-63) + 23. 21- 58 .23
=23.{(-63)+21-58}
=23.(-100)
= -2300
-2300
Tik cho mk nha..............cảm ơn rất nhiều
