Find the magnitude of v if
V = 3i -6j -2k
I get 7 but my book says 2 sq. roots of 11
Please show a few steps as to how to get the answer! Thank you!!!!

√(3^2 + 6^2 + 2^2) = √(9+36+4) = √49 = 7
Your book is apparently working the problem for 2i-6j-2k. It happens. Some underpaid grad student didn't have quite enough coffee to keep his eyes open.

..........._____________
||v|| =√3² + (-6)² +(-2)²
..........._______
.......=√9+36+4 =√49 = 7
If V is actually 2i -6j -2k
then result would be √44 =2√11
did you read or copy it wrong, or
did your book actually make an error?
