Question

If n(A)=2. (B) =m and the number of relations from A to B is 64 the the value of m is​

Answer 1

Answer:

n(A) = 2

n(B) = m =?

The total number of relation from A to B is 2^pq

P= 2 and

q= m

number of relation = 64 [Given]

» 2^pq = 64

or, 2^2m = 64

or, 2^2m = 2^6 [ 64 = 8x8 = 2^3.2^3=2^6]

Or, 2m = 6 [comparing Powers]

Or, m = 3

Therefore the value of m is 3.
