Square root of 4 minus square root of 21 (√4-√21)

√4 - √21

Here we will walk you through the process of calculating the difference between the square root of 4 and the square root of 21. Essentially, we will calculate √4 - √21.

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 21:
√21 ≈ 4.58258

3. Subtract the square root of 21 from the square root of 4:
2 - 4.58258 = -2.58258

Therefore, the result of subtracting the square root of 21 from the square root of 4 is approximately -2.58258.

√4 - √21 ≈ -2.58258

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

2 - √21
