Post-UTME Mathematics 2019 Objective — Question 29

Question 29 of 50 from the Post-UTME Screening (Post-UTME) Mathematics 2019 Objective paper, with the correct answer and a full explanation.

If U = (1,2,3,6,7,8,9,10) is the universal set, E = (10,4,6,8,10) and F = is odd (x:x²=2ⁿ). Find (E∩F), where x is the complement of a set

Explanation

F requires x²=2ⁿ with x odd, which has no valid even members in common with E, so E∩F = ∅.
