How are fractions presented in mixed form? How do you write an index form?

The remaining index law from arithmetic deals with dividing powers of the same base. The index law for the quotient of powers of the same base.

The module Multiples , Factors and Powers developed the law in the form, ‘To divide powers of the same base, subtract the indices ’. In other words, the expressions have index or indices in fraction form. A fraction is a part of a whole.
