Chapter 9.4, Problem 1E

A vector in three dimensions can be written in either of two forms: in coordinate form as v = 〈a₁, a₂, a₃〉 and in terms of the __________ vectors i, j, and k as v = _______________. The magnitude of the vector v is | v | = _______________. So $\langle 4,-2,4\rangle =\boxed{}i+\boxed{}j+\boxed{}k$ and $7j-24k=\langle \boxed{},\boxed{},\boxed{}\rangle$.
