Question

A={a,b,p},B={2,3} and c={p,q,r,s}then n((AuC)×B)=​

Answer 1

Answer:

AuC= {a,b,p} u {p,q,r,s}

u is all to write.

= {a,b,p,q,r,s}

(AuC)×B) = {a,b,p,q,r,s}×{2,3}

= (a ,2)( b, 2 )( p ,2)(q ,2,)( r, 2)( S,2)

n=A={a,b,p},

B={2,3}

c={p,q,r,s}

n=3 (A,B,C)

= n((AuC)×B)

= 3((a ,2)( b, 2 )( p ,2)(q ,2,)( r, 2)( S,2))

= (3a,6 )(3b,6)( 3p,6)(3q,6)( 3r,6)( 3s,6)
