a) \(\left(-8\right)-\left[\left(-5\right)+8\right]\)
\(=\left(-8\right)+5-8\)
\(=\left(-3\right)-8\)
\(=-11\)
b) \(25.134+25.\left(-34\right)\)
\(=25.\left[134+\left(-34\right)\right]\)
\(=25.100\)
\(=2500\)
mk nhanh nhất đó nha
a) (-8)-[(-5)+8]
= (-8)-3
= -11
b) 25.134+25.(-34)
=25.[134+(-34)]
=25.100
=2500
k mik nha, happy new years
a) (-8 ) - [(-5) + 8 ]
= (-8) - 3
= -11
b) 25.134 + 25 . (-34)
= 25 . [ 134 + (-34)]
= 25 . 100
= 2500
a) ( - 8 ) - [ ( - 5 ) + 8 ]
= ( - 8 ) - 3
= - 11
b) 25 . 134 + 25 . ( - 34 )
= 25 . [ 134 + ( - 34 ) ]
= 25 . 100
= 2500
a) (-8)-[(-5)+8]
=(-8)-3
=-11
b) 25.134+25.(-34)
=25.(-34+134)
=25.100
=2500
