(a) Predicate: 10d is an integer
The domain is . In fact, integers are closed under multiplication, and 10 is an integer. So, if d is an integer, 10d is a multiplication between integers, and thus an integer.
(c)
Since 1 and 4 are both squares, we have
And we deduce that x must be between 1 and 2. But since negative numbers become positive when squared, the numbers between -2 and -1 are also fine. So, the domain is
Predicates (b) and (d) are identical to (a) and (c)
