This
unit deals with powers (or indices) of positive whole numbers. It
begins by looking at powers of natural base numbers and then looks at
some special cases where the base number or power is 0. Afterwards, it
deals with negative base numbers. We
will then look at carrying out different operations with powers such
as multiplication, division and raising to another power. At
the end of the unit we shall take an initial look at fractions as
indices when we talk about square roots.
