Exponentiation is a mathematical operation, written a^{n}, involving two numbers, the base a and the exponent n. When n is a positive integer, exponentiation corresponds to repeated multiplication:

a^{1} = a

a^{2} = a × a

a^{3} = a × a × a

a^{4} = a × a × a × a

and so on.

and so on.

A rational number is a number which can be expressed as a ratio of two integers. Non-integer rational numbers (commonly called fractions) are usually written as the vulgar fraction a / b , where b is not zero. a is called the numerator, and b the denominator.
