Question

Put this number into two significant figures.
4.55*10^-12

Answer 1

4.6x10^-12 or 0.0000000000046

The significant figures start when you get to the first non-zero number after the decimal.

Answer 2

That's what I thought it would be but I guess I got that number wrong cause my answer is still coming out incorrect! Thank you for your help though!

Answer 3

No prob sorry to hear that it is not coming up correctly.

Answer 4

Is there any way it would be like 5.0 * 10^-12 to make two sig figs?

Answer 5

It could be, but based on that number of 4.55 I would still say 4.6 is better, but yes it could be 5.0 if they specify rounding to the nearest whole number.

Answer 6

Thank you!
