Significant Figures
posted by Carl .
I'm having a hard time with significant figures. Any help would be appreciated.
The first one is 0.0000000502. I put that it has three significant figures. Is this correct?
The other numbers I haven't a clue about are:
5.52
299,792,458
206,265
I get the jist of it, but I'm still struggling with the concept.
