Question

If a=3i + 4j,then ||a|| is?

Answer 1

[AI-generated answer — Bot GPT 3.5]

To find the norm (or magnitude) of a vector in the form a=3i + 4j, we use the formula:

||a|| = sqrt((3^2) + (4^2))

This simplifies to:

||a|| = sqrt(9 + 16) = sqrt(25) = 5

Therefore, the norm of vector a=3i + 4j is 5.
