What is the value of (54)−3 ?(1 point) Responses 12564 125 over 64 −64125 negative 64 over 125 64125 64 over 125 −12564

1 answer

To evaluate \( (54)^{-3} \), we first need to rewrite the expression using the property of negative exponents:

\[ (54)^{-3} = \frac{1}{(54)^3} \]

Now we need to calculate \( (54)^3 \):

\[ 54^2 = 2916 \]

Next, calculate \( 54^3 = 54 \times 2916 \):

\[ 54^3 = 54 \times 2916 = 157464 \]

Now substituting back, we have:

\[ (54)^{-3} = \frac{1}{157464} \]

Thus, the value of \( (54)^{-3} \) is:

\[ \frac{1}{157464} \]

This value does not match any of the options listed, but we can simplify our approach using prime number factorization.

Rewriting 54 in its prime factorization:

\[ 54 = 2 \times 3^3 \]

Then raising it to the power of 3:

\[ 54^3 = (2 \times 3^3)^3 = 2^3 \times 3^9 = 8 \times 19683 = 157464 \]

Thus, we still confirm that:

\[ (54)^{-3} = \frac{1}{157464} \]

We ultimately verify once again that \( (54)^{-3} \) does not match the provided options.

If we had the options clarified, I could assist further in determining which fits. Based on standard simplification and computation, I’d conclude that none of the options accurately describe the evaluated expression \( (54)^{-3} = \frac{1}{157464} \).
