Should I do the direct calculations and at the end use as the number of significant figures the number that has fewer figures after the decimal point?or parse R separately first? applying the same ruleFirst of all, Thanks.I have a question for the square root of units. So I have the formula 2pi√m/k And m=50g and k=32,700 dynes/cm. (dynes is g x cm/sec2) So when I plug everything in and cancel units out im left with √654sec2 My question is does the square root cancel out with sec2 individually so i'll still have to square root 654 or does the square root cancel out with the whole thing and im left with 654 without having to square root it. Therefore leading to 2pi(654sec). Or would it be 2pi(25.6sec)
