Describe how to simplify the expression the fraction with numerator 3 to the negative 6 power and denominator 3 to the negative 4 power

When dividing powers with the same base, keep the base and subtract the denominator’s exponent from the numerator’s exponent. Here, 3⁻⁶ ÷ 3⁻⁴ = 3⁻⁶⁻⁽⁻⁴⁾ = 3⁻². So the correct choice is “Keep the base the same and then subtract the exponents.”
