Question

If A= {2, 3, 4} then no. of elements in P (A)

are_____________.
​

Answer 1

Answer:

It’s worth to NOTE that A ×B doesn’t always equal to B×A

Why? Well let’s use P and Q ‘s elements.

We will have 2 idenependent Set:

P x Q = {(1, 2), (1, 3), … ,(3, 4)}

Q x P ={ (2, 1), (2, 2), …, (4, 3)}

They will clearly give you two different geometrical object on xoy cordinate axis.
