Final answer:
To simplify the expression (c⁻⁹)/(4), rewrite it as 1/(4c⁹).
Step-by-step explanation:
To simplify the expression (c⁻⁹)/(4), we can rewrite it as c⁻⁹/4. Since the exponent is negative, we can move the base to the denominator and change the sign of the exponent. This gives us 1/c⁹ * 1/4.
Next, we can combine the fractions by multiplying the numerators and the denominators. This gives us 1/(c⁹ * 4).
Finally, we can simplify the expression further by multiplying the exponents. This gives us the final expression: 1/(4c⁹).
