In mathematics, exponentiation is an operation involving two numbers: the base and the exponent or power. Exponentiation is written as b n, where b is the base and n is the power; this is pronounced as "b (raised) to the (power of) n ".
From this definition, we can deduce some basic rules that exponentiation must follow as well as some hand special cases that follow from the rules. In the process, we'll define exponentials $x^a$ for exponents $a$ that aren't positive integers.
Transcript. Exponents represent repeated multiplication, making numbers grow quickly. For example, 2 to the 3rd power means multiplying three 2's together, resulting in 8. This concept differs from multiplication, which is simply repeated addition.
Exponentiation is a process or operation of taking the exponent of a number. If x is an integer raised to n which is a positive integer, then it can be expressed as x^n. Learn more about exponentiation in this article.
Exponents. The exponent of a number says how many times to use the number in a multiplication. In 82 the "2" says to use 8 twice in a multiplication, so 82 = 8 × 8 = 64. In words: 8 2 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared".
Exponentiation is a way of shortening the process/equation of repeatedly multiplying many copies of a number. An exponent is a number or symbol, placed above and to the right of the expression to which it applies, that indicates the number of times the expression is used as a factor.

6 days ago · Exponentiation is the process of taking a quantity b (the base) to the power of another quantity e (the exponent). This operation most commonly denoted b^e. In TeX, the Wolfram Language, and many other computer languages, exponentiation is denoted with a caret, i.e., as b^e.
Negative Exponents Rules. Let \ (a\) and \ (b\) be positive real numbers and \ (n\) be any real number. Rule 1. \ (a^ {-n}=\dfrac {1} {a^n}\) Rule 2. \ (\dfrac {1} {a^ {-n}}=a^n\) Rule 3. \ (\left (\dfrac {a} {b}\right)^ {-n}=\left (\dfrac {b} {a}\right)^n\) Negative exponents are combined in several different ways.
An exponent is a number that tells us how many times the base it is attached to is used as a factor. Exponentiation is a mathematical operation in which the base is raised to an exponent. In 5 3, 5 is the base and 3 is the exponent.
