The image contains a list of mathematical expressions involving exponents and scientific notation. The task appears to be to simplify or evaluate each expression.

Let’s go through each one step by step:

---

1. 2⁴ × 2² × 2⁶

When multiplying powers with the same base, add the exponents:

2⁴⁺²⁺⁶ = 2¹²

2¹² = 4096

Correct answer: 4096

---

2. 5³ × 5⁴ × 5²

Again, same base → add exponents:

5³⁺⁴⁺² = 5⁹

5⁹ = 1,953,125

Correct answer: 1,953,125

---

3. 3⁵ × 3⁷ × 3⁻⁹

Add exponents: 5 + 7 - 9 = 3

So, 3³ = 27

Correct answer: 27

---

4. 4⁶ × 4⁻² × 4⁻¹

Add exponents: 6 - 2 - 1 = 3

4³ = 64

Correct answer: 64

---

5. 7⁴ × 7⁻³ × 7²

Add exponents: 4 - 3 + 2 = 3

7³ = 343

Correct answer: 343

---

6. 10⁵ × 10⁻⁴ × 10³

Add exponents: 5 - 4 + 3 = 4

10⁴ = 10,000

Correct answer: 10,000

---

7. (2 × 10³) × (3 × 10⁴)

Multiply coefficients: 2 × 3 = 6

Multiply powers of 10: 10³ × 10⁴ = 10⁷

So, 6 × 10⁷ = 60,000,000

Correct answer: 60,000,000

---

8. (5 × 10²) × (4 × 10⁻¹)

Coefficients: 5 × 4 = 20

Powers of 10: 10² × 10⁻¹ = 10¹

So, 20 × 10¹ = 200

Correct answer: 200

---

9. (6 × 10⁵) × (2 × 10⁻³)

Coefficients: 6 × 2 = 12

Powers of 10: 10⁵ × 10⁻³ = 10²

So, 12 × 10² = 1,200

Correct answer: 1,200

---

10. (8 × 10⁴) × (5 × 10⁻²)

Coefficients: 8 × 5 = 40

Powers of 10: 10⁴ × 10⁻² = 10²

So, 40 × 10² = 4,000

Correct answer: 4,000

---

All answers have been verified.

Final Answer:
4096, 1953125, 27, 64, 343, 10000, 60000000, 200, 1200, 4000
