Question

If A = φ,n(B) = 4, then n( A×B) is​

Answer 1

Step-by-step explanation:

If A = φ,n(B) = 4, then n( A×B) is

We know that if A is a set with m elements i.e., n(A)=m,

We know that if A is a set with m elements i.e., n(A)=m, then, n[P(A)]=2

We know that if A is a set with m elements i.e., n(A)=m, then, n[P(A)]=2 m

We know that if A is a set with m elements i.e., n(A)=m, then, n[P(A)]=2 m .

We know that if A is a set with m elements i.e., n(A)=m, then, n[P(A)]=2 m .If A=ϕ, then n(A)=0

We know that if A is a set with m elements i.e., n(A)=m, then, n[P(A)]=2 m .If A=ϕ, then n(A)=0∴n[P(A)]=2

We know that if A is a set with m elements i.e., n(A)=m, then, n[P(A)]=2 m .If A=ϕ, then n(A)=0∴n[P(A)]=2 o

We know that if A is a set with m elements i.e., n(A)=m, then, n[P(A)]=2 m .If A=ϕ, then n(A)=0∴n[P(A)]=2 o =1

We know that if A is a set with m elements i.e., n(A)=m, then, n[P(A)]=2 m .If A=ϕ, then n(A)=0∴n[P(A)]=2 o =1Hence, P(A) has one element
