What is an equivalent expression for −(b1/4)^12 ?(1 point)

-b1/3
-b^3
-b^-3
1/b^3

1 answer

To simplify the expression \(-\left(\frac{b}{4}\right)^{12}\), we will execute the exponent first.

Let's start with the base inside the parentheses:

\[ \left(\frac{b}{4}\right)^{12} = \frac{b^{12}}{4^{12}} \]

Now, substituting back, we have:

\[ -(\frac{b^{12}}{4^{12}}) = -\frac{b^{12}}{4^{12}} \]

Next, let's identify \(4^{12}\):

\[ 4^{12} = (2^2)^{12} = 2^{24} \]

So the expression becomes:

\[ -\frac{b^{12}}{2^{24}} \]

To express \(\frac{b^{12}}{2^{24}}\) in a different way, we use the negative sign outside to change the exponent:

\[ -\frac{1}{b^{-12}} \text{ or } -b^{12} \cdot 2^{-24} \]

However, the choices you have given don’t correspond to the simplification we conducted.

Now let's take a look at your answer options:

  • \(-b^{1/3}\)
  • \(-b^3\)
  • \(-b^{-3}\)
  • \(\frac{1}{b^3}\)

The original expression in terms of its complete form does not seem to match directly with any of those options.

However, if the expression required was instead \(-b^{12}\) or if any transformation was initiated from there, I can clarify further.

To conclude: none of the answer choices here, based on the expression \(-\left(\frac{b}{4}\right)^{12}\), appear equivalent. Would you like to check the original requirements if there were arithmetic operations requested on a different form or recheck the problem?
