What Is Exponentiation?
Exponentiation is a mathematical operation written as:
aⁿ
This means multiplying the base number by itself multiple times.
Example:
2³ = 2 × 2 × 2 = 8

What Is an Exponent?
Exponentiation is a mathematical operation where a number is multiplied by itself a certain number of times.
an = a × a × a × …
The base a is multiplied by itself n times.
Example:
25 = 2 × 2 × 2 × 2 × 2 = 32
Exponent Rules
Multiplying Exponents
When exponents with the same base are multiplied, add the exponents.
am × an = am+n
Example:
23 × 24 = 27 = 128
Dividing Exponents
When exponents with the same base are divided, subtract the exponents.
am ÷ an = am-n
Example:
25 ÷ 23 = 22 = 4
Power of an Exponent
When a power is raised to another exponent, multiply the exponents.
(am)n = amn
Example:
(23)2 = 26 = 64
Negative Exponents
A negative exponent creates the reciprocal of the base.
a-n = 1 / an
Example:
2-3 = 1 / 23 = 1 / 8 = 0.125
Zero Exponent
Any non-zero number raised to the power of zero equals 1.
a0 = 1
Example:
50 = 1
Fractional Exponents
Fractional exponents represent roots.
a1/n = n√a
Examples:
- 161/2 = 4
- 271/3 = 3
