Question

Which number(s) satisfy a ∩ c? 16, 81 1, 16, 81 1, 4, 9, 16, 25, 36, 49, 81, 100 1, 4, 9, 16, 25, 36, 49, 64, 81, 100

Answer 1

Explanation:

B: 1, 16, 81

WHY?

Set A is perfect squares from A to 100:

1^2 = 1

2^2 = 4

3^2 = 9

4^2 = 16

5^2 = 25

6^2 = 36

7^2 = 49

8^2 = 64

9^2 = 81

10^2 = 100

Set A = 1, 4, 9, 16, 25, 36, 49, 64, 81, 100

Set C is perfect fourths

1^4 = 1

2^4 = 16

3^4 = 81

4^4 = 254 (This is greater than 100)

Set C = 1, 16, 81

Hope this helps :)
