A vector in the opposite direction to 2i-4j+4k (magnitude 6) must be m(-2i+4j-4k) with m>0. Square root of 736 is not even a rational number, let alone an integer. Last edited: Jan 18, 2022

It does have modulus root(736) and each component (i,j,k) has been scaled into the opposite direction, even if they haven't all been scaled by the same factor.
