Question

1. Let n(A)=m. Then the total number of elements in the P(A) is
A) m to power n
B)nto power m-1
C) mn - 1
D) 2 to power m​

Answer 1

Step-by-step explanation:

For any set A such that n(A)=n

then number of all relations on A is 2n2

the total number of Relations that can be defined from a set A to B is the number of possible subsets of A×B. If n(A)=p and n(B)=q then n(A×B)=pq and the number of subsets of A×B = 2pq.

So, option (d) 2 n to the power n...is your answer..ok...
