How many significant zeros are in the number 1000?

four
so 1000. is our four-significant-figure answer. (from rules 5 and 6, we see that in order for the trailing zeros to “count” as significant, they must be followed by a decimal. Writing just “1000” would give us only one significant figure.) 8.
