The question is what numbers satisfy A ∩ C.

The symbol ∩ means intersection, .i.e. you need to find the numbers that belong to both sets A and C. Those numbers might belong to the set C or not, because that is not a restriction.

Then lets find the numbers that belong to both sets, A and C.

Set A: 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

=> A = {1, 4, 9, 16, 25, 36, 49, 64, 81, 100}

Set C: perfect fourths

1^4 = 1
2^4 = 16
3^4 = 81

C = {1, 16, 81?

As you see, all the perfect fourths are perfect squares, so the intersection of A and C is completed included in A. this is:

A ∩ C = C or A ∩ C = 1, 16, 81

On the other hand, the perfect cubes are:

1^3 = 1
2^3 = 8
3^3 = 27
4^3 = 81

B = {1, 8, 27, 81}

That means that the numbers 1 and 81 belong to the three sets, A, B, and C.

In the drawing you must place the number 16 inside the region that represents the intersection of A and C only, and the numbers 1 and 81 inside the intersection of the three sets A, B and C.

The meaning of the inverted U in this item is intersection. This means that the elements of the set A ∩ C should be a perfect square and also a perfect-fourths. The answer to this item is equal to 1, 16, 81. The answer is letter B.

b.  1, 16, 81

Step-by-step explanation:

A is numbers that are perfect squares and C is numbers that are perfect fourths.

This means that A∩C is numbers that are both perfect squares and perfect fourths.

Out of the numbers from 1 to 100, the only ones this applies to is 1 (1² = 1 and 1⁴ = 1), 16 (4² = 16 and 2⁴ = 16) and 81 (9² = 81 and 3⁴ = 81).
