Question

verify that -[x+y]=[-x]+[-y],when :​

Answer 1

Answer:

(i)x=2/3,y=5/7

-[2/3+5/7]=[-2/3]+[-5/7]

-[14+15/21]=-2/3-5/7

-29/21=-14-15/21

-29/21=-29/21

hence verified

(ii)x=-2/3,y=-5/7

-[-2/3+(-5/7)=[-(-2/3)+[-(-5/7)]

-[-14-15/21]=2/3+5/7

-[-29/21]=14+15/21

29/21=29/21

hence verified
