Answer:
5.2 centimicro meter or 5.2 cμm
Explanation:
Prefixes allow scientists report numbers logically depending on the order of the magnitude of the numbers. For example to represent 4 x 10⁻³m, it is more handy to say : 4 millimetre, where milli- is the prefix for 10⁻³.
Common prefixes are:
deci = 10⁻¹ deca = 10¹
centi = 10⁻² hecto = 10²
milli = 10⁻³ kilo = 10³
micro = 10⁻⁶ mega = 10⁶
nano = 10⁻⁹ giga = 10⁹
pico = 10⁻¹² terra = 10¹²
femto = 10⁻¹⁵ peta = 10¹⁵
Now, let's represent the given diameter: 5.2 x 10⁻⁸ m
Since the 10⁻⁸ prefix is not common (or maybe doesn't even exist), the way around this is to break it into bits such as:
10⁻⁸ = 10⁻² x 10⁻⁶ [10⁻² = centi, 10⁻⁶ = micro ]
10⁻⁸ = centimicro
Therefore, 5.2 x 10⁻⁸ m becomes 5.2 centimicro meter.
The symbol is 5.2 cμm
Where c = centi, μ = micro.
