Question

PLEASE HELP!!!!!!!!!!!!!!

Answer 1

The first answer is correct:

`\{(1)/(3),-3.45,√(9)\}`

Explanation:

Since
`(1)/(3), -3.45, √(9)=3` are all rational numbers, the set that contains those numbers is the set of rational numbers.

In the second set, number
`√(37)` is irrational number since it can not be written as quotient.

Also in the third and fourth set, numbers
`√(44)` and
`√(2)` are irrational numbers.

Therefore, the first answer is correct.
