Answer 1

Given universal set =
`{ -6, -5 3/4, -sqrt4, -3/5, -3/8, 0, 4/5, 1, 1 2/3, sqrt8, 3.01, π, 8.47 }`

We need to find the set of non-negative integers.
Set of non-negative integers consists of zero and the natural numbers.
The set of non-negative integers is Z⁺ and Z⁺ = { 0, 1, 2, 3,...... }
Here the set of integers is U ∩ Z⁺ = {0, 1}
