A
\[(-x)^3\]
(Choice B)
\[x^{-{3}}\]
B
\[x^{-{3}}\]
(Choice C)

\[x^{^{\frac1{3}}}\]
C

\[x^{^{\frac1{3}}}\]

Answer 1

To find the equivalent expression for \(\dfrac{1}{x^{3}}\), we can rewrite it using the properties of exponents.

The expression \(\dfrac{1}{x^{3}}\) can be rewritten as:

\[
x^{-3}
\]

So, the equivalent expression is:

(Choice B) \(x^{-{3}}\)

Thus, the answer is:

**B: \(x^{-{3}}\)**
