Power Rule for Exponents

What is the Power Rule for exponents?
The “power rule for exponents” refers to the rule for simplifying an expression where a power is raised to another power. It’s also sometimes called the “power of a power rule”.

The Power Rule for exponent states that when we raise a power to a power, we can multiply the exponents while keeping the base the same.

Formula:
(a^m)ⁿ = a^{m × n}
Where:
(a) is the base (any real number or variable).
(m) and (n) are the exponents (any real numbers).

How to Apply the Power Rule:

1. Identify the base and the exponents.
2. Multiply the inner exponent by the outer exponent.
3. The base remains the same.

Example:
(3²)⁵ = 3^{2 × 5} = 3¹⁰
