Answer 1

Answer:

Step-by-step explanation:

Factors of 12 are 1,2,3,4,6,12. So, the prime factors of 12 are 2,3.

   We write the set A in roster form as A={2,3} and hence n(A)=2.

(ii) B={x:x∈W,x≤5}. In Tabular form, B={0,1,2,3,4,5}.  

The set B has six elements and hence n(B)=6 THIS IS YOUR ANSWER
