Question

How many significant digits are there in the measurement 9478.983560 cm?

Answer 1

Hi, I just learned about this in my Algebra II class. There are actually 10 significant numbers in this number. Any 0 before a whole number is NOT a significant number but all whole numbers are significant and the 0 behind the whole number is also significant so all 10 numbers are significant.

Answer 2

Hi,

There are 10 significant digits in the measurement of 9478.983560 cm. A significant number is a number that is not a zero, however, in this problem you see there is one zero and that counts as a significant number because it is after a whole number.

In conclusion, a significant number is a number that is not a zero, however the only exception to this rule is that it must be after a whole number for it it to count as significant.

Thanks a lot for posting and I hope this helped. :)
