Exponential Form: Exponentiation is a mathematical operation, written as , involving two numbers, the base and the exponent . When is a positive integer, exponentiation corresponds to repeated multiplication of the base: that is , is the product of multiplying bases:
In that case,, is called the power of , or raised to the power .
When is a negative integer and is not zero, is naturally defined as
Let be any non-zero real number and and be positive integers:
If , then , provided and
