Let P = {x:x is a prime natural number is less than 9} and Q = {2, 4}, then find `PxxQ`.

Let A={x:x inNN and x is a prime number in [10,19]} and B = {2,3}, find AxxB .

(i) Let's write 4 negative whole numbers less than - 12

Examine whether the following statements are true or false: { x : x is an even natural number less than 6} ⊂ { x : x is a natural number which divides 36}

How many natural numbers are less than 8 ? Write down the numbers.

Write the relation R= {(x,x^3): x is a prime number less than 10) in roster form.

Write the following sets in roster form (i) B= {x:x is a natural number smaller than 6} C= {x:x is a two-digit natural number such that the sum of its digits is 8). (iii) D= {x : x is a prime mimber which is a divisor of 60}. E= {x:x is an alphabet in BETTER}.

Determine a natural number which is less by 12 than its square.

If A = { x : x is a natural number }, B = { x : x is an even natural number} C = { x : x is an odd natural number} and D = { x : x is a prime number }, find B ∩ D

If A = { x : x is a natural number }, B = { x : x is an even natural number} C = { x : x is an odd natural number} and D = { x : x is a prime number }, find B ∩ C

If A = { x : x is a natural number }, B = { x : x is an even natural number} C = { x : x is an odd natural number} and D = { x : x is a prime number }, find A ∩ B
