Answer: 2.333333 ..., the first answer shown
Explanation:
The graphic asks which numbers lie between the square roots of 5 and 6, so I will answer that, since I believe that was your intention.
≈ 2.236 and
≈ 2.450, so any correct answer must be between these two numbers.
2.33333... lies between the two square roots, so it is a valid answer.
π ≈ 3.1416, so it is too big to lie between the square roots.
5/2 = 2.5, so it is also too big to lie between the square roots.
2.1 is less than 2.236, so it is too small to lie between the square roots.
The first answer, 2.3333 .... is the only valid answer.
I hope this helps.
