Exponentiation
Exponentiation is a mathematical operation, written as b^n, involving two numbers, the base b and the exponent n. When n is a positive integer, exponentiation corresponds to repeated multiplication of the base: that is, b^n is the product of multiplying n bases:
- b^n = b × b × ... × b n factors.
Definition[edit | edit source]
Exponentiation is a mathematical operation, written as b^n, involving two numbers, the base b and the exponent n. When n is a positive integer, exponentiation corresponds to repeated multiplication of the base: that is, b^n is the product of multiplying n bases:
- b^n = b × b × ... × b n factors.
Properties[edit | edit source]
Exponentiation has properties that it shares with other operations on numbers. Some of these properties are:
- b^0 = 1 for any b (except b = 0), because any number except 0 raised to the power of 0 is 1.
- b^1 = b for any b, because any number raised to the power of 1 is the number itself.
- b^n = b × b^n−1 for any b and any positive integer n, because any number raised to a power is that number times the number raised to one less than that power.
Applications[edit | edit source]
Exponentiation is used in a wide variety of contexts, including in algebra, calculus, geometry, and computer science. It is also used in practical applications such as calculating interest rates, population growth, and radioactive decay.
