Compute the absolute, exponential distance between two given prefixes:

16) kilo and femto ---> 10^{3} and 10¯^{15} give a total absolute distance of 10^{18}

17) milli and micro ---> 10¯^{3} and 10¯^{6} give a total absolute distance of 10^{3}

18) micro and mega ---> 10¯^{6} and 10^{6} give a total absolute distance of 10^{12}

19) centi and pico ---> 10¯^{2} and 10¯^{12} give a total absolute distance of 10^{10}

20) nano and kilo ---> 10¯^{9} and 10^{3} give a total absolute distance of 10^{12}

21) deci and tera ---> 10¯^{1} and 10^{12} give a total absolute distance of 10^{13}

22) pico and micro ---> 10¯^{12} and 10¯^{6} give a total absolute distance of 10^{6}

23) kilo and giga ---> 10^{3} and 10^{9} give a total absolute distance of 10^{6}

24) femto and centi ---> 10¯^{15} and 10¯^{2} give a total absolute distance of 10^{13}

25) milli and centi ---> 10¯^{3} and 10¯^{2} give a total absolute distance of 10^{1}

Some people are always looking for rules to memorize to help them. Notice that when the two prefixes are from the same side (two negatives or two positives), the answer is the absolute difference between the two. If the two prefixes cross over (as in one positive and one negative), then it is the absolute sum.

OK, but what if the problem involves the base unit, as in "What is the absolute difference between nano and no prefix?" I guess the answer is that it doesn't matter because the absolute difference between 10¯^{9} and 10^{0} is the same as the absolute sum.
