Question

if n(A)=2, n (b) =m and the number of relations from A to B is 64 , then the value of m is​

Answer 1

Answer:

Given that n(A)=2 and n(B)=m

So,

2

2m

=64

2

2m

=2

6

On comparing powers of 2 we get,

2m=6

m=3

Step-by-step explanation:

Correct option is

B

3

The number of relations between sets can be calculated using 2

mn

where m and n represent

the number of members in each set.
