Question

Математика: 1)a-(b+c+d-c-f); 2)a+(b+c+d-c-f); 3)-c-d+c+f); 4) a+(-b-c-d-c-f) ; 5)a-(b-c+d-c+f) ; 6)+c-d+c+f); 7)a+(b-c_d-c+f) ; 8)a+(b=c-d+c+f)

lisafoxxxxxxxx · Answer

1)a-(b+c+d-c-f)=a-b-c-d+c+f=a-b-d+f2)a+(b+c+d-c-f)=a+b+c+d-c-f=a+b+d-f3)a-(-b-c-d+c+f)=a+b+c+d-c-f=a+b+d-f4)a+(-b-c-d-c-f)=a-b-c-d-c-f=a-b-2c-d-f5)a-(b-c+d-c+f)=a-b+c-d+c-f=a-b+2c-d-f6)a-(-b+c-d+c+F)=a+b-c+d-c-f=a+b-2c+d-f7)a+(b-c-d-c+f)=a+b-c-d-c+f=a+b-2c-d+f8)a+(b+c-d+c+f)=a+b+c-d+c+f=a+b+2c-d+f...
