Final answer:
To evaluate the given exponential expression, rewrite the negative exponent as a fraction and simplify the expression.
Step-by-step explanation:
To evaluate the given exponential expression, we need to understand how negative exponents work. Negative exponents indicate that the number should be moved to the denominator and the sign of the exponent should be changed to positive. In this case, we have 3 raised to the power of -3, which can be rewritten as 1/3^3. Computing this, we get 1/27. Finally, we multiply the result by 3, so the final value is 3/27, which simplifies to 1/9.
