Square root of 2 minus square root of 128 (√2-√128)

√2 - √128

Here we will walk you through the process of calculating the difference between the square root of 2 and the square root of 128. Essentially, we will calculate √2 - √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 2:
√2 ≈ 1.41421

2. Calculate the square root of 128:
√128 ≈ 11.31371

3. Subtract the square root of 128 from the square root of 2:
1.41421 - 11.31371 = -9.8995

Therefore, the result of subtracting the square root of 128 from the square root of 2 is approximately -9.8995.

√2 - √128 ≈ -9.8995

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

√2 - 8√2
