Since I can't view or access images directly, I can't see the specific numbers in your image. However, you've provided a list of square roots, and the task is to determine whether each number is
rational or
irrational.
Let me go through the general rule and then solve each one based on what’s typically found in such worksheets:
---
🔹 Rational vs Irrational Numbers:
- A
rational number can be expressed as a fraction $ \frac{p}{q} $ where $ p $ and $ q $ are integers and $ q \neq 0 $. Rational numbers either terminate or repeat in decimal form.
- An
irrational number cannot be expressed as a simple fraction. Its decimal form neither terminates nor repeats.
For
square roots, we know:
- If the number under the square root is a
perfect square, then the square root is
rational.
- If it's
not a perfect square, then the square root is
irrational.

Now let’s evaluate each expression assuming this is the list from your image:
1. $ \sqrt{25} $
→ $ 25 = 5^2 $, so $ \sqrt{25} = 5 $ →
Rational
2. $ \sqrt{2} $
→ 2 is not a perfect square →
Irrational
3. $ \sqrt{64} $
→ $ 64 = 8^2 $ → $ \sqrt{64} = 8 $ →
Rational
4. $ \sqrt{3} $
→ Not a perfect square →
Irrational
5. $ \sqrt{7} $
→ Not a perfect square →
Irrational
6. $ \sqrt{8} $
→ $ 8 = 4 \times 2 $, $ \sqrt{8} = 2\sqrt{2} $ →
Irrational
7. $ \frac{3}{10} $
→ This is a fraction →
Rational
8. $ \sqrt{44} $
→ 44 is not a perfect square →
Irrational
9. $ \sqrt{26} $
→ Not a perfect square →
Irrational
10. $ \sqrt{324} $
→ $ 324 = 18^2 $ → $ \sqrt{324} = 18 $ →
Rational
11. $ \pi $
→ Pi is a well-known
irrational number →
Irrational
12. $ \sqrt{37} $
→ Not a perfect square →
Irrational
13. $ \sqrt{81} $
→ $ 81 = 9^2 $ → $ \sqrt{81} = 9 $ →
Rational
14. $ \sqrt{8} $
→ Already evaluated above →
Irrational

Let me know if any of the expressions were different (e.g., $ \sqrt{0.25} $, $ \sqrt{1/4} $, etc.), and I can adjust accordingly!
