Here we will show you how to calculate 4 square root of 20, which is the same as 4√20, which again is the same as 4 times √20. In other words, we will calculate 4 × √20.
We will not only calculate the 4 square root of 20 decimal answer, but we will also calculate 4 square root of 20 simplified. We will start by calculating the decimal answer to 4 square root of 20, as follows:
1. Find the square root of 20:
√20 ≈ 4.472136
2. Multiply 4 by the square root of 20:
4 × 4.472136 = 17.888544
4√20 ≈ 17.888544
To get the answer to 4 square root of 20 simplified, we first determine if √20 can be simplified, and then we multiply what is outside the radical (√) by 4 to get 4 square root of 20 simplified.
√20 can be simplifed to 2√5. Therefore, 4 square root of 20 simplifed can be calculated like this:
4 × 2 × √5 = 8√5
4√20 simplified = 8√5
