Solve the following exercise:
Let's simplify the expression. First, we'll reduce the fraction under the square root, then we'll calculate the result of the root:
Therefore, the correct answer is option B.

Solve the following exercise:
\( \sqrt{\frac{2}{4}}= \)
Simplifying first makes the calculation much easier! Instead of working with larger numbers like 225 and 25, you get the simpler , which is clearly 3.
That's fine! Simplify as much as possible first, then take the square root. For example, , but .
Think: "25 times what equals 225?" Since 25 × 9 = 225, we know 225 ÷ 25 = 9. You can also use long division if needed!
You can, but try to do it by hand first! Recognizing that 225 = 15² and 25 = 5² helps you see patterns and builds your number sense.
Always start by simplifying the fraction under the square root. This single step will make most problems much clearer and easier to solve!
