Because the SI prefixes strictly represent powers of 10, they should not be used to represent powers of 2. This chart covers powers of ten from tens to billions. You don't have to know the nature of a unit to convert, for example, from kilo-unit to mega-unit.All metric prefixes are powers of 10. Good effort! To alleviate this ambiguity, prefixes for binary multiples have been adopted by the International Electrotechnical Commission (IEC) for use in information technology. Subsequent worksheets require the student to expand terms in increasingly larger scientific notation, starting with coefficients that are whole values and then progressing through decimal coefficients and negative values. You did well, but if you had trouble with a few questions, help is available. P. peta. Ex 3.
