Looking at the image you uploaded, it’s a
“Review Math Worksheet – Grade 6” focused on
square roots.
The specific problem highlighted in the green box is:
>
√16 = ?
---
✔ Solution:
√16 = 4
---
📚 Explanation:
The symbol
√ means “
square root”.
- The
square root of a number is a value that, when
multiplied by itself, gives the original number.
- So, we’re looking for a number that, when squared (× itself), equals 16.
Let’s test:
- 1 × 1 = 1
✘
- 2 × 2 = 4
✘
- 3 × 3 = 9
✘
-
4 × 4 = 16 ✔
Therefore,
√16 = 4
> 💡 Note: Technically, -4 is *also* a square root of 16 because (-4) × (-4) = 16. But in elementary math (like Grade 6), unless otherwise specified, we usually mean the
principal (positive) square root. So the answer is
4.

🔁 Extra Tip:
You can memorize perfect squares to solve these quickly:
| Number | Square |
|--------|--------|
| 1 | 1 |
| 2 | 4 |
| 3 | 9 |
|
4 |
16 |
| 5 | 25 |
| 6 | 36 |
| ... | ... |
So whenever you see √16, think: “What number times itself is 16?” →
4

✔ Final Answer:
4
