To simplify the square root of 20, you can break it down into its prime factors. The number 20 can be expressed as:
- 20 = 4 × 5
- 4 is a perfect square (2 × 2).
Now, you can rewrite the square root of 20 using this factorization:
√20 = √(4 × 5)
Next, apply the property of square roots that allows you to separate the factors:
√20 = √4 × √5
Since the square root of 4 is 2, you can simplify further:
√20 = 2√5
Thus, the simplified form of the square root of 20 is 2√5.
