Square root of 7 minus square root of 18 (√7-√18)

√7 - √18

Here we will walk you through the process of calculating the difference between the square root of 7 and the square root of 18. Essentially, we will calculate √7 - √18.

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 18:
√18 ≈ 4.24264

3. Subtract the square root of 18 from the square root of 7:
2.64575 - 4.24264 = -1.59689

Therefore, the result of subtracting the square root of 18 from the square root of 7 is approximately -1.59689.

√7 - √18 ≈ -1.59689

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

√7 - 3√2
