The correct steps to simplify an exponential expression using the Quotient Rule of Integer Exponents are:
- Check if the bases are the same.
- If they are the same, subtract the exponents of the numerator and denominator.
- Write the resulting expression in exponential form.
So, the second option you provided is the correct one:
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.
