SI prefixes are used to prepare decimal multiples. and you estimate that it was about 5/10 of the way between them. So the estimated digit of the two if we have 40 500 miles as represented, the zeros are not significant just the four and the five R. So the estimated digit would be the five. Significant digits (also called significant figures or "sig figs" for short) indicate the precision of a measurement. centi = 10e-2 e. Copper Recall: the number of significant figures includes one estimated digit. 100 has one significant figure (and it's a number 1). 0000237910 00000 n Thus, there are only two significant digits from the 2 & 5. Write its atomic symbol. We report its length as 44.5 cm.
