Hi jumana,

I can give you a few ideas. First of all exponential form is a way of displaying mathematical expressions using exponents. For example Pythagoras' Theorem, when expressed in algebraic form uses the exponent 2. For some specific examples go to the Quandaries and Queries page on Math Central and use the Quick Search to search for the term math beyond school pythagoras.

Compound interest is another place where exponents are used.
