How many sig figs is this following thing?

Question

.0003040 how many sig figs is that.. .im guessing 4..? i think.. 20 characters... more characters to suffice the dumb thing

Answer 1

4

Answer 2

4 !!!!

Answer 3

Four. The zeroes ahead of the 3 establish the order of magnitude and are not significant figures. The zero at the end is a significant figure: It means that the value intended is not as big as 0.0003041 and not as small as 0.0003039. If  the last zero was missing, it would mean the value intended was not as big as 0.000305 and not as small as 0.000303 -- quite a different thing.

Answer 4

3.040 * 10^(-4)

four

Answer 5

that's four sig figs

Answer 6

The answer is actually three significant figures. The number that you submitted above can be simplified to 3.04*10^4. The zero on the end is not needed.
