Square root of 7 minus square root of 8 (√7-√8)

√7 - √8

Here we will walk you through the process of calculating the difference between the square root of 7 and the square root of 8. Essentially, we will calculate √7 - √8.

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 7:
√7 ≈ 2.64575

2. Calculate the square root of 8:
√8 ≈ 2.82843

3. Subtract the square root of 8 from the square root of 7:
2.64575 - 2.82843 = -0.18268

Therefore, the result of subtracting the square root of 8 from the square root of 7 is approximately -0.18268.

√7 - √8 ≈ -0.18268

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

√7 - 2√2
