The correct steps to follow to simplify an exponential expression using the Quotient Rule of Integer Exponents are:
Check if the bases are the same; if they are, subtract the exponents of the numerator and denominator (leave as-is otherwise); and write the resulting expression in exponential form.
This means that you only apply the Quotient Rule when the bases of the exponential expressions are the same, in which case you subtract the exponents (i.e., \( a^m / a^n = a^{m-n} \)). If the bases are different, you cannot simplify the expression using the Quotient Rule.
