Solution:-

given by:- (i) A = The set of all even natural numbers less than 20.

A = { 2 ,4,6,8,10,12,14,16,18,} ans

= A = {x:x is even natural number x > 20} ans

(ii) B = {y : y = 2n
1 , n ! N, n ≤ 5}

= B ={ 1 , 2 , 6 , 24 , 120} ans

(iii) C = {x : x is perfect cube, 27 < x < 216}

= C ={ , 4^3 , 5^3 , } ans

(iv) D = {x : x ! Z, –5 < x ≤ 2}

= D =  {-4,-3,-2,-1,0,1,2} ans
