SUMMARY
To make vector A = a(3.0i + 4.0j) a unit vector, the constant 'a' must be determined such that the magnitude of vector A equals one. The correct value of 'a' is 1/5, as this ensures that the magnitude of the vector is normalized to one. This conclusion is based on the definition of a unit vector, which requires a magnitude of exactly one.
