Square root of 7 minus square root of 72 (√7-√72)

√7 - √72

Here we will walk you through the process of calculating the difference between the square root of 7 and the square root of 72. Essentially, we will calculate √7 - √72.

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 72:
√72 ≈ 8.48528

3. Subtract the square root of 72 from the square root of 7:
2.64575 - 8.48528 = -5.83953

Therefore, the result of subtracting the square root of 72 from the square root of 7 is approximately -5.83953.

√7 - √72 ≈ -5.83953

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

√7 - 6√2
