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, then proceed to the next step; if they are not, the expression can't be simplified using the Quotient Rule in this context and you would leave it as-is.
-
Subtract the exponents of the numerator and denominator. Write the resulting expression in exponential form.
So, to summarize, the appropriate choice is:
- 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.
