Square root of 21 minus square root of 5 (√21-√5)

√21 - √5

Here we will walk you through the process of calculating the difference between the square root of 21 and the square root of 5. Essentially, we will calculate √21 - √5.

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 5:
√5 ≈ 2.23607

3. Subtract the square root of 5 from the square root of 21:
4.58258 - 2.23607 = 2.34651

Therefore, the result of subtracting the square root of 5 from the square root of 21 is approximately 2.34651.

√21 - √5 ≈ 2.34651

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

√21 - √5
