If A={Positve perfect squares less than 100} and B={Positve perfect cuber less than 100} , then find `n(A cap B)`

IF A={Prime numbers less than 10}, and B={positive odd number less than 10}, then find (i) A cap B (ii) B-A.

Find the perfect squares between 100 and 150

Given that A= {Perfect cubes between 10 and 100} B={Perfect squares between 10 and 100} and B={Perfect squares between 10 and 100}.Find n(A cap B)

Let A={x: x is a positive multiple of 3 less than 100} and B={x: x is a prime number less than 20}, then n(A) + n(B) is equal to:

The set of prime numbers less than 100 is :

If A = {x : x is a prime less than 20} and B = {x : x is a whole number less than 10}, then verify n(A uu B) = n(A) + n(B) - n(AnnB) .

What is the largest perfect number less than 50?

A={all primes less than 20} B={ all whole numbers less than 10} then A cap B =…………
