2 square root of 20 (2√20)

Here we will show you how to calculate 2 square root of 20, which is the same as 2√20, which again is the same as 2 times √20. In other words, we will calculate 2 × √20.

We will not only calculate the 2 square root of 20 decimal answer, but we will also calculate 2 square root of 20 simplified. We will start by calculating the decimal answer to 2 square root of 20, as follows:

1. Find the square root of 20:
√20 ≈ 4.472136

2. Multiply 2 by the square root of 20:
2 × 4.472136 = 8.944272

2√20 ≈ 8.944272

To get the answer to 2 square root of 20 simplified, we first determine if √20 can be simplified, and then we multiply what is outside the radical (√) by 2 to get 2 square root of 20 simplified.

√20 can be simplifed to 2√5. Therefore, 2 square root of 20 simplifed can be calculated like this:

2 × 2 × √5 = 4√5

2√20 simplified = 4√5
