Problem 18E

Show that if A and B are sets |A| = |B|, then  Step-by-Step Solution:

Step 1:

In the given problem we have to prove that  if A and B sets, then  Step 2:

Let suppose A and B are the sets.

x A

Similarly

x Where |A| =|B| means the number of the element is same in both the set.

For example: A={a,b,c}

B={d,e,f}

|A| =number of element in set A =3 similarly |B| is also having 3 element

Therefore        |A|=|B|

Step 3 of 3
