Final answer:
The question seems to be mixing the concept of 10 codes used in radio communication with scientific notation used in mathematics. Since the context points to converting numbers to scientific notation, the question doesn't properly apply to 10 radio codes. However, explanations for converting numbers to and from scientific notation have been provided.
Step-by-step explanation:
The question seems to be about two different subjects. The 10 codes refer to radio communication codes often used by police, but since options provided such as 10^-6 or 10^-8 resemble scientific notation, the question is likely about scientific notation. Scientific notation is a way of expressing numbers that are too big or too small to be conveniently written in decimal form. In the context of scientific notation, given the options, in service could be referring to a code that signifies that a unit is back in service, which is not represented by scientific notation. However, the notion of being 'back in service' or a similar status update doesn't have a counterpart in scientific notation, which strictly pertains to numerical representation. Nevertheless, if we focus on scientific notation, which suits the subject and control codes given, converting an ordinary number to scientific notation, or vice versa, involves moving the decimal point to create a new number between 1 and 10, then multiplying by 10 raised to the number of places the decimal was moved. If the students needs conversion exercises similar to the patterns of the given options, here are some examples:
