Shift a decimal place to the left, so the exponent for base 10 is 1. Therefore, we obtain:
2.68 x 10 mm.
5,000 mm in Scientific Notation = 5 x 103mm
3.7501 × 107 mm or 3.7501E7 mm
9.4 kilometers = 9,400,000 millimeters:9,400,000 mm in Scientific Notation = 9.4 x 106mm
3.6E-6 mm = 3.6E-9 m is the scientific notation.
When we say "convert", we mean "write it a different way, but don't change its actual size". Like '1 foot' and '12 inches' ... same length, different description. You can't do anything that involves "the third power" without changing the actual size of a quantity. So that's not a "convert" kind of thing.
(4 times 10-7) mm.
1.54 × 104 mm
4.5834 x 10-3.
7.0043 x 10^9
3 x 10-5 mm
6.3 x 106 mm
There are 3.6*10^6 of them.
