Set Representation | MCQs
-
A. {1,5,25}
-
B. None of these
-
C. {-5,5}
-
D. {-5}
Explanation
The set-builder form A = {x | x ∈ ℤ ∧ x² = 25} means x is an integer whose square is 25.
The integers satisfying this are x = -5 and x = 5, so A = {-5, 5}.
-
A. E=(2,1,4)
-
B. E=(1,4,2)
-
C. E=(2,4,1)
-
D. E=(1,2,4)
Explanation
The given equation is a permutation of the numbers, where [E] = {4, 1, 2} represents the set of values.
The correct permutation is E = (2, 1, 4), which means:
