Answer 2

To determine the validity of the equation \( 10^{-13} = -10^{-\frac{1}{3}} \), we need to analyze both sides using the properties of exponents.

The left side is:
\[
10^{-13} = \frac{1}{10^{13}}.
\]

The right side can be rewritten using the Negative Exponent Rule:
\[
-10^{-\frac{1}{3}} = -\frac{1}{10^{\frac{1}{3}}}.
\]

This means the equation becomes:
\[
\frac{1}{10^{13}} = -\frac{1}{10^{\frac{1}{3}}}.
\]

Clearly, \( \frac{1}{10^{13}} \) is a positive number, while \( -\frac{1}{10^{\frac{1}{3}}} \) is a negative number. Thus, these two sides are not equal.

Therefore, the correct response is:

**False, because the Negative Exponent Rule requires that the number be rewritten as a quotient, not as a negative value.**

Answer 3

Let's analyze and simplify the left side of the equation \( 3^{-5} \cdot (81^{\frac{1}{4}})^3 \cdot 3^{-4} \) to see if it's equal to \( 3^{-6} \).

### Step 1: Simplifying \( (81^{\frac{1}{4}})^3 \)

First, we calculate \( 81^{\frac{1}{4}} \):
\[
81 = 3^4 \implies 81^{\frac{1}{4}} = (3^4)^{\frac{1}{4}} = 3^{4 \cdot \frac{1}{4}} = 3^1 = 3.
\]
Now substituting back, we have:
\[
(81^{\frac{1}{4}})^3 = 3^3 = 27.
\]
So, our left side becomes:
\[
3^{-5} \cdot 3^3 \cdot 3^{-4}.
\]

### Step 2: Combining the Exponents

Using the properties of exponents:
\[
3^{-5} \cdot 3^3 \cdot 3^{-4} = 3^{-5 + 3 - 4} = 3^{-6}.
\]

### Conclusion

Now we have simplified the left-hand side to \( 3^{-6} \), which is exactly equal to the right-hand side \( 3^{-6} \).

### Result

The statement:
\[
3^{-5} \cdot (81^{\frac{1}{4}})^3 \cdot 3^{-4} = 3^{-6}
\]
is **True**.

Thus, the correct response is:

**True. (81^{\frac{1}{4}})^3 = 3^2 and \( 3^{-10}\) / \(3^{-4} = 3^{-6} \).**
