QuestionFind v\|\mathbf{v}\|. v=3i4j\mathbf{v}=3 \mathbf{i}-4 \mathbf{j} | v=\mathbf{v} \|= \square (Type an exact answer, using radicals as needed. Simplify your answer.)

Studdy Solution
Simplify the expression:
v=32+(4)2=9+16=25\|\mathbf{v}\| = \sqrt{3^2 + (-4)^2} = \sqrt{9 + 16} = \sqrt{25}
The magnitude of the vector v\mathbf{v} is:
5\boxed{5}
