Answer 1

Answer:

Indices provide a compact algebraic notation for repeated multiplication. For example, is it much easier to write 35 than 3 × 3 × 3 × 3 × 3.

Once index notation is introduced the index laws arise naturally when simplifying numerical and algebraic expressions. Thus the simplificiation 25 × 23 = 28 quickly leads

to the rule am × an = am + n, for all positive integers m and n.

As often happens in mathematics, it is natural to ask questions such as:

Can we give meaning to the zero index?

Can we give meaning to a negative index?

Can we give meaning to a rational or fractional index?

These questions will be considered in this module.
