Square root of 21 minus square root of 6 (√21-√6)

√21 - √6

Here we will walk you through the process of calculating the difference between the square root of 21 and the square root of 6. Essentially, we will calculate √21 - √6.

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 21:
√21 ≈ 4.58258

2. Calculate the square root of 6:
√6 ≈ 2.44949

3. Subtract the square root of 6 from the square root of 21:
4.58258 - 2.44949 = 2.13309

Therefore, the result of subtracting the square root of 6 from the square root of 21 is approximately 2.13309.

√21 - √6 ≈ 2.13309

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

√21 - √6
