Square root of 2 minus square root of 78 (√2-√78)

√2 - √78

Here we will walk you through the process of calculating the difference between the square root of 2 and the square root of 78. Essentially, we will calculate √2 - √78.

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 2:
√2 ≈ 1.41421

2. Calculate the square root of 78:
√78 ≈ 8.83176

3. Subtract the square root of 78 from the square root of 2:
1.41421 - 8.83176 = -7.41755

Therefore, the result of subtracting the square root of 78 from the square root of 2 is approximately -7.41755.

√2 - √78 ≈ -7.41755

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