Answer 2

Answer:

Option (a) A and B are equal

Step-by-step explanation:

The given sets are

A = {1, 2, 3, 4}

B = { x is positive integer and $x^{2}$ < 20 }

  = { x > 0 / $x^{2}$ < 20 }

The positive integers whose squares are less than 20 are 1, 2, 3, 4

Therefore,

B = { 1, 2, 3, 4}

Since A and B have same elements A = B

Hence the given sets

A = {1, 2, 3, 4} , B = { x is positive integer and $x^{2}$ < 20 } are equal
