Definition
In mathematics, the power of an exponent refers to the number of times a base number is multiplied by itself. It is represented as:
a^n
where:
a is the base (the number being multiplied),
n is the exponent (the number of times the base is multiplied by itself).
Example:
In 3^4, the number 3 is the base, and the exponent is 4, which means:
3^4 = 3 • 3 • 3 • 3 = 81
So, the power 3^4 means that the base 3 is multiplied by itself 4 times.
The exponent also defines some special rules for mathematical operations like zero exponent (a^0 = 1, for any non-zero a), and negative exponents (a^-n = 1/a^n).
