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

Answers

  1. Answer:
    Step-by-step 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 🙂
