√2 - √84


Subtracting Square Roots

Here we will walk you through the process of calculating the difference between the square root of 2 and the square root of 84. Essentially, we will calculate √2 - √84.

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 84:
√84 ≈ 9.16515

3. Subtract the square root of 84 from the square root of 2:
1.41421 - 9.16515 = -7.75094

Therefore, the result of subtracting the square root of 84 from the square root of 2 is approximately -7.75094.

√2 - √84 ≈ -7.75094

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

√2 - 2√21
