Câu 1:72.(-2)2+(-2) 2 .28
= (-2)2 . ( 72 + 28 )
= 4 . 100
= 400
Câu 2: (-25).(75-45)-75.(45-25)
= (-25) . 75 + 25 . 45 - 75 . 45 + 75 . 25
= 25 . 45 - 75 . 45
= 45 . ( 25 - 75 )
= 45 . -50
= -2250
Câu 3:a+1 là ước của 5
\(\Rightarrow\)a + 1 \(\in\){ 1 ; -1 ; 5 ; -5 }
\(\Rightarrow\)a \(\in\){ 0 ; -2 ; 4 ; -6 }
Vậy a \(\in\){ 0 ; -2 ; 4 ; -6 }
