Question

if set A is the set of all even numbers between 0 and 20 and set B is the set of powers of 2 between 0 and 20, then A ∩ B =

Answer 1

This means A intersection B. Let's state both of the sets here.
0,2,4,6,8,10,12,14,16,18,20 in set A.
1, 2, 4, 8, 16 in set B.

The common terms are 2,4,8 and 16. So, a intersection b is {2,4,8,16}

Answer 2

{ 2, 4, 8, 16} is 0 a even no..i wonder coz 2^0 is also 0 i hv read it somewhere!!

Answer 3

@payal111 2^0 = 1

Answer 4

kohli u r right my mistake..

Answer 5

A={2,4,6,8,10,12,14,16,18,20}
B={1,2,4,8,16}
Thus AnB={2,4,8,16}
