Introduction
When dealing with exponents, it's essential to understand the rules that govern their behavior, especially when it comes to quotient of powers. In this article, we will delve into the world of exponents and explore the value of $m$ in the quotient of powers $\frac{9{-3}}{92}=\frac{1}{9^m}$ and the value of $n$ in the quotient of powers $\frac{x{-4}}{x{-6}}=x^n$.
The Quotient of Powers Rule
The quotient of powers rule states that when dividing two powers with the same base, we subtract the exponents. Mathematically, this can be represented as:
where $a$ is the base and $m$ and $n$ are the exponents.
Applying the Quotient of Powers Rule to the First Equation
Let's apply the quotient of powers rule to the first equation:
Using the quotient of powers rule, we can rewrite the equation as:
Since the bases are the same, we can equate the exponents:
