Square root of 4 minus square root of 20 (√4-√20)

√4 - √20

Here we will walk you through the process of calculating the difference between the square root of 4 and the square root of 20. Essentially, we will calculate √4 - √20.

First, we need to find the square root of each number individually. Then we will subtract one from the other. Below is the step-by-step calculation:

1. Calculate the square root of 4:
√4 = 2

2. Calculate the square root of 20:
√20 ≈ 4.47214

3. Subtract the square root of 20 from the square root of 4:
2 - 4.47214 = -2.47214

Therefore, the result of subtracting the square root of 20 from the square root of 4 is approximately -2.47214.

√4 - √20 ≈ -2.47214

To make things even more convenient, we have also expressed the result in its simplest radical form:

2 - 2√5
