Square root of 7 minus square root of 90 (√7-√90)

√7 - √90

Here we will walk you through the process of calculating the difference between the square root of 7 and the square root of 90. Essentially, we will calculate √7 - √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 7:
√7 ≈ 2.64575

2. Calculate the square root of 90:
√90 ≈ 9.48683

3. Subtract the square root of 90 from the square root of 7:
2.64575 - 9.48683 = -6.84108

Therefore, the result of subtracting the square root of 90 from the square root of 7 is approximately -6.84108.

√7 - √90 ≈ -6.84108

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

√7 - 3√10
