(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

What's the magnitude of A, when A = 4i+4j ?

2. Relevant equations

3. The attempt at a solution

The answer is sqrt(32), but do Sig Figs matter for this type of problem? Should I write it as 5.66? Or do I leave it as sqrt(32).

P.S. - I know in a Math class I would write it as sqrt(32), but this is for a Physics class. Thanks all.
