√4 - √128


Subtracting Square Roots

Here we will walk you through the process of calculating the difference between the square root of 4 and the square root of 128. Essentially, we will calculate √4 - √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 4:
√4 = 2

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

3. Subtract the square root of 128 from the square root of 4:
2 - 11.31371 = -9.31371

Therefore, the result of subtracting the square root of 128 from the square root of 4 is approximately -9.31371.

√4 - √128 ≈ -9.31371

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

2 - 8√2
