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.
