Square root of 7 minus square root of 128 (√7-√128)

√7 - √128

Here we will walk you through the process of calculating the difference between the square root of 7 and the square root of 128. Essentially, we will calculate √7 - √128.

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 128:
√128 ≈ 11.31371

3. Subtract the square root of 128 from the square root of 7:
2.64575 - 11.31371 = -8.66796

Therefore, the result of subtracting the square root of 128 from the square root of 7 is approximately -8.66796.

√7 - √128 ≈ -8.66796

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

√7 - 8√2
