Answer 2

To calculate the expression |(-2; 4; -6) + (-2; 0; 1)|, you need to find the magnitude of the vector resulting from the addition of the two given vectors. The magnitude of a vector (a; b; c) is given by the formula:

|v| = sqrt(a^2 + b^2 + c^2)

Let's calculate the expression step by step:

First, add the corresponding components of the two vectors: (-2; 4; -6) + (-2; 0; 1) = (-2 + -2; 4 + 0; -6 + 1) = (-4; 4; -5)

Now, calculate the magnitude using the formula: |(-4; 4; -5)| = sqrt((-4)^2 + 4^2 + (-5)^2) = sqrt(16 + 16 + 25) = sqrt(57)

So, the magnitude of the vector (-4; 4; -5) is approximately sqrt(57), which is approximately 7.55.
