It looks like you've uploaded a page from a math textbook (Holt Algebra 1), specifically the
Solutions Key for Chapter 7: *Exponents and Polynomials*. This page contains answers to various problems, including simplifying expressions with exponents, evaluating powers, and working with polynomials.
However, you mentioned that there's an image with a task — but
no image was actually included in your message. The text you provided is just a scanned or copied version of the solutions key.

🔍 What I Can Do:
Since you said “I uploaded an image with a task,” but only shared this text, here’s what I can help with:
1.
If you're asking for explanations of any of the problems on this page (e.g., how they were solved), I can walk through them step-by-step.
2.
If you want me to solve a specific problem from this list (like #5, #13, or #28), I can do that.
3.
If you have a separate problem that wasn't included here, please describe it or upload it again.

✔ Example Explanation:
Let’s take one problem as an example:
#### Problem:
#13. $-12^2$
Answer: $-(12 \cdot 12) = -144$
Explanation:
- The expression is $-12^2$, which means
negative of 12 squared.
- Exponentiation comes before negation unless parentheses indicate otherwise.
- So, $12^2 = 144$, then apply the negative sign: $-144$.
- If it were $(-12)^2$, that would be $(-12)(-12) = 144$ — different!
✔ So the answer is
-144, not 144.

Another example:
#### Problem:
#2a. $10^{-4} = \frac{1}{10^4} = \frac{1}{10,000}$
Explanation:
- A negative exponent means reciprocal: $a^{-n} = \frac{1}{a^n}$
- So $10^{-4} = \frac{1}{10^4} = \frac{1}{10,000}$

📌 Let Me Know:
Please clarify:
- Are you asking about
one specific problem?
- Or do you need help understanding
how to simplify exponents?
- Or was there a
different task in the image you meant to include?
Once I know what you're looking for, I’ll give you a clear, detailed explanation!
