Square root of 4 minus square root of 84 (√4-√84)

√4 - √84

Here we will walk you through the process of calculating the difference between the square root of 4 and the square root of 84. Essentially, we will calculate √4 - √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 4:
√4 = 2

2. Calculate the square root of 84:
√84 ≈ 9.16515

3. Subtract the square root of 84 from the square root of 4:
2 - 9.16515 = -7.16515

Therefore, the result of subtracting the square root of 84 from the square root of 4 is approximately -7.16515.

√4 - √84 ≈ -7.16515

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

2 - 2√21
