Question

List all the elements of each of the sets given below:
(i) `A={x:x=2n,n in N and n le 5}`.
(ii) `B={x:x=2n+1,n in W and n lt 5}`.
(iii) `C={x:x =(n)/(n), n in N and n lt 6}`.
(iv) `D={x:x= n^2, n in N and 2 le n le 5}`.
(v) `E={x:x in Z and x^2=x}`.
(vi) `F={x:x in Z and (1)/(2) lt x (13)/(2)}`.
(vii) `G={x:x =(1)/((2n-1)), n in N and 1 le nle 5}`.
(viii) `H={x:x in Z, |x|le 2}`.

Answer 1

Correct Answer - (i) `A= {2,4,6, 8,10}`
(ii) ` B={1,3,5,7,9}`
(iii) `C={1,(1)/(2),(1)/(3), (1)/(4),(1)/(5)}`
(iv) `D= { 4,9, 16,25}`
(v) `E={0,1}`
(vi) `F={0,1,2,3,4,5,6}`
`G={ 1, (1)/(3).(1)/(5),(1)/(7),(1)/(9)}`
(viii) `H= { -2, -1, 0,1 2}`
