Square root of 9 minus square root of 84 (√9-√84)

√9 - √84

Here we will walk you through the process of calculating the difference between the square root of 9 and the square root of 84. Essentially, we will calculate √9 - √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 9:
√9 = 3

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

3. Subtract the square root of 84 from the square root of 9:
3 - 9.16515 = -6.16515

Therefore, the result of subtracting the square root of 84 from the square root of 9 is approximately -6.16515.

√9 - √84 ≈ -6.16515

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

3 - 2√21
