Many ideas have been discussed in the last three lessons. You have acquired the tools and techniques you will need for handling other number systems. Now it’s time to review what you have learned.
We have had these definitions for cases where n is a positive whole number:
bn
= b × b × b × ⋯ × b (bused as a factorntimes)
b3
= b × b × bb2
= b × bb1
= bb0
= 1 ( providedbis not equal to 0)
b − 1
= (1)/(b)b − 2
= (1)/(b2)b − n
= (1)/(bn)
