Question

12,104 x 0.0000000072= 0.00009 My Answer Is Rounded to thousandth Am I RIGHT?

Answer 1

For the significant digits, you want to do the smallest amount of whichever of your calculations have the least significant digits. Since you only have 2 different values, and of the two, then 0.0000000072 has less significant digits, with 2, your final answer should have 2 significant digits as well.

Answer 2

You Jus Confused Me More.

Answer 3

Which of the two numbers have less significant figures?

Answer 4

what does significant figures mean?

Answer 5

That means when you do a calculation, it is the amount of digits that you round to. Of your two values, which has more digits that are useful to the calculation itself?

Answer 6

So My Rounding Is Off.

Answer 7

Well for your answer, yes. You would want to round to two numbers, instead of just one. That is because of your two values, the 0.00000000072 has only 2 useful digits, while the 12104 has 5, therefore, you would want to round to 2 digits.

Answer 8

I would not complicate the problem with significant figures as it deals more w/ accuracy of measurement rather than simply rounding.

The "thousandth" place is third place after the decimal. To represent a number this small you would have to use a scientific notation.

Answer 9

8.71488 is what I got

Answer 10

\[8.715 x 10^{-5}\]

Answer 12

8.71488 x 10^-5 is your answer?
