Question

If n(A*B) =6 and A = {1,3} then n(B) is what

Answer 1

if cardinal no multiplication in both the sets is 6 and cardinal no of set a is given 2 as the element in set are only 2 given 1 and 3

therefore in b it would be

6/2 =3

the cardinal no of set b is 3 or n(B) =3

hope it helps u

mark me brainliest pls

Answer 2

The value of n(B) = 3.

Step-by-step explanation:

Since we have given that

n(A*B) = 3

And (A) = {1,3}

So, n(A)  = 2

So, it becomes,

$n(A*B)=n(A).n(B)\\\\6=2\times n(B)\\\\\dfrac{6}{2}=n(B)\\\\3=n(B)$

Hence, the value of n(B) = 3.
