Final answer:
Due to typos in the question, it is not possible to calculate a precise answer. Generally, the magnitude of a resultant vector is the square root of the sum of the squares of its components.
Step-by-step explanation:
The question seems to be concerned with finding the magnitude of a resultant vector from given vectors in physics. Unfortunately, the question contains typos that make it unclear what the specific vectors are. In general, to find the magnitude of the resultant vector, you would need to add the given vectors together, which can involve adding their components along the x, y, and z dimensions, and then find the magnitude of the resulting vector using the equation R = √(x^2 + y^2 + z^2), where R is the resultant vector's magnitude, and x, y, z are its components along the respective axes. It would be helpful to restate the question with the correct vector components for a precise calculation.
