To approximate the number 0.0000000529177 of a millimeter and match it to the given options, we would look at the significant digits starting from the left:
The number is 0.0000000529177 mm.
If we round to the nearest ten-billionth of a millimeter (which seems to be the precision level of your options), it would look like this:
- The next digit after 5 is 2, which is less than 5, so we do not round up.
- Therefore, the rounded number would be: 0.00000005 mm.
So the best approximation from the given options is:
0.00000005 mm.
