Square root of 4 minus square root of 90 (√4-√90)

√4 - √90

Here we will walk you through the process of calculating the difference between the square root of 4 and the square root of 90. Essentially, we will calculate √4 - √90.

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 90:
√90 ≈ 9.48683

3. Subtract the square root of 90 from the square root of 4:
2 - 9.48683 = -7.48683

Therefore, the result of subtracting the square root of 90 from the square root of 4 is approximately -7.48683.

√4 - √90 ≈ -7.48683

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

2 - 3√10
