7) \( \sqrt{125} \)

Did you know that \( \sqrt{125} \) is not just a number but can be simplified? You can break it down: \( \sqrt{125} = \sqrt{25 \times 5} = \sqrt{25} \times \sqrt{5} \). Since \( \sqrt{25} = 5 \), it follows that \( \sqrt{125} = 5\sqrt{5} \). This means it’s equal to about 11.18 if you want a decimal approximation! When dealing with square roots, a common mistake is forgetting to simplify radical expressions. Make sure to look for perfect squares within the radicand (the number under the square root). This can make your problems much easier and clearer. Next time you encounter a square root, see if you can break it down into smaller components!
