Square root of 20 minus square root of 7 (√20-√7)

√20 - √7

Here we will walk you through the process of calculating the difference between the square root of 20 and the square root of 7. Essentially, we will calculate √20 - √7.

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 20:
√20 ≈ 4.47214

2. Calculate the square root of 7:
√7 ≈ 2.64575

3. Subtract the square root of 7 from the square root of 20:
4.47214 - 2.64575 = 1.82639

Therefore, the result of subtracting the square root of 7 from the square root of 20 is approximately 1.82639.

√20 - √7 ≈ 1.82639

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

2√5 - √7
