Can you do the following in math: √(2^2 + 4^2 - 6^2)= √2^2 + √4^2 - √6^2 = 2 + 4 - 6

Especially when applied to finding the magnitude of a vector

√(2^2 + 4^2 - 6^2) ≠ √2^2 + √4^2 - √6^2

√(4 + 16 - 36) ≠ √4 + √16 - √36

√-16 ≠ 2 + 4 - 6

√-16 ≠ 0

And √-16 is not existence in real numbers!

0

Its 0 duh
