Definition: Power of power Rule

Power of power Rule: This rule states that when a base raised to a power is then raised to another power, the exponents are multiplied and the base remains the same.

Explanation:

If you have a base, say x, raised to two exponents, say m and n, then \$(x^m)^n=x^(mn)\$.

Definition: Negative exponent Rule

Negative exponent Rule: The negative exponent rule states that a base with a negative exponent should be written as its reciprocal. This makes the exponent positive.

Explanation:

This rule deals with negative exponents.If you have x raised to the power of -n, it’s equivalent to \$1/(x^n)\$.
