√8 - √20


Subtracting Square Roots

Here we will walk you through the process of calculating the difference between the square root of 8 and the square root of 20. Essentially, we will calculate √8 - √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 8:
√8 ≈ 2.82843

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

3. Subtract the square root of 20 from the square root of 8:
2.82843 - 4.47214 = -1.64371

Therefore, the result of subtracting the square root of 20 from the square root of 8 is approximately -1.64371.

√8 - √20 ≈ -1.64371

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

2√2 - 2√5
