R = {x ∈ Z | x is divisible by 2}
T = {x ∈ Z | x is divisible by 6}. Then T ⊂ R
पर्याय
True
False
उत्तर
This statement is True.
Explanation:
R and T can be represented in roster form as follows:
R = {…,-8, -6, -4, -2, 0, 2, 4, 6, 8,….}
T = {…,-18, -12, -6, 0, 6, 12, 18,….}
Since, every element of T is present in R.
So, T ⊂ R
