It looks like you’ve uploaded a page featuring math exercises on exponents, powers, and square roots. Here's a quick breakdown of the topics:

1. Simplifying powers and exponents
   Problems include combining, multiplying, and simplifying expressions using exponent rules (e.g., laws like $a^m \cdot a^n = a^{m+n}$).

2. Calculations involving powers
   Exercises ask for direct calculation of expressions involving multiple powers and roots.

3. Simplifying to the lowest form
   Questions focus on reducing expressions like sums or products of powers to their simplest form.

4. Square roots
   Introduction to square roots, including basic examples like $\sqrt{36} = 6$ and $\sqrt{169} = 13$.

Would you like me to solve some specific problems, explain a topic in more detail, or clarify any of the exponent rules used here? Let me know!

Related Questions:

1. How do you simplify $a^m \cdot a^n$ and $\frac{a^m}{a^n}$?
2. Can you explain how to convert roots into exponents (e.g., $\sqrt{x} = x^{1/2}$)?
3. What are the rules for adding and subtracting powers with the same base?
4. How do you handle negative exponents (e.g., $a^{-n}$)?
5. Why is the square root of a number always non-negative?

Tip: When simplifying exponents, always remember to combine like terms using the same base and apply rules carefully to avoid errors.
