The equivalent expression is: (C)
$(1)/(3^9 \cdot 6^(18))$.

To simplify the given expression, we can apply the rules of exponents.

First, we raise 3 to the power of 3 and 6 to the power of 6, individually:

3^3 = 27 and 6^6 = 46656.

Next, we multiply these two values together:

27 * 46656 = 1259712.

Now, we raise the result to the power of -3:

1259712^(-3).

To simplify this expression, we can rewrite it as the reciprocal of the base raised to the positive exponent:

(1 / 1259712^3).

This can be further simplified by raising the base to the power of 3:

(1 / (1259712 * 1259712 * 1259712)).

Finally, we can simplify the expression by multiplying the denominators:

1 / (1954890816015872).

Given:

The given expression is
\left(3^(3) \cdot 6^(6)\right)^(-3)

We need to determine the equivalent expression.

Equivalent expression:

The equivalent expression can be determined by solving the given expression.

Let us apply the exponent rule,
a^(-b)=(1)/(a^(b))

Thus, we get;


(1)/(\left(3^(3) \cdot 6^(6)\right)^(3))

Again, applying the exponent rule,
(a \cdot b)^(n)=a^(n) b^(n)

Thus, we have;


(1)/(\left(3^(3))^3 \cdot (6^(6)\right)^(3))

Simplifying, we get;


(1)/(3^(9) \cdot 6^(18))

Thus, the equivalent expression is
(1)/(3^(9) \cdot 6^(18))

Hence, Option C is the correct answer.
