Explanation:
The expression that we have is:
And we need to use the quotient rule to find the exponent of x.
Step 1. The quotient rule or division rule for exponents is:
Where A is the case and m and n are the exponents. We need to apply this rule both to x and y in our expression.
Step 2. Applying the quotient rule the result is:
Step 3. Solving the subtractions in the exponents:
The exponent on x is 2.
Answer:
2
