Scientific notation, powers and prefixes Creative Commons: Attribution Non-commercial Share Alike page 1 of 12 Author: Dr J A Koenig 1. Multiplying and dividing with powers of 10. Engineering notation or engineering form is a version of scientific notation in which the exponent of ten must be divisible by three (i.e., they are powers of a thousand, but written as, for example, 10 6 instead of 1000 2).As an alternative to writing powers of 10, SI prefixes can be used, which also usually provide steps of a factor of a thousand. For example, the base unit of length is the metre. Some prefixes are also used in digital communications and computer technology but they have a slightly different value because they are based on a power of 2. The same is true for the metric system or SI units. The standard set of prefixes are in powers of ten. Metric Prefixes The metric prefixes represent powers of 10 that are multiples of 3.
