Yes, radical 20 (√20) can be simplified.
Here's how:
√20 can be broken down into its factors. We are looking for perfect square factors to simplify the radical.
- Find the factors: The factors of 20 are 1, 2, 4, 5, 10, and 20.
- Identify perfect square factors: Among these factors, 4 is a perfect square (2 x 2 = 4).
- Rewrite the radical: √20 can be rewritten as √(4 x 5).
- Simplify: √(4 x 5) = √4 x √5 = 2√5
Therefore, the simplified form of √20 is 2√5.
