The question asks which exponential notation equals 343. Calculating each option:

- **A. 3⁷**: \(3^7 = 2187\), which is much larger than 343.
- **B. 7³**: \(7^3 = 7 \times 7 \times 7 = 343\), matching the target number.
- **C. 7⁴⁹** and **D. 294⁴⁹**: Both are astronomically large values, far exceeding 343.

Thus, the correct answer is **B. 7³**.

Explanation:
343 is equal to 7 raised to the power of 3 (7 * 7 * 7 = 343). Therefore, the correct exponential notation for 343 is 7^3.

deepseekv3 To determine which number written in exponential notation is equivalent to 343, let's evaluate each option:

1. **343** is the number we need to express in exponential form.

2. Evaluate the options:
- **A. \(3^7\)**: \(3^7 = 3 \times 3 \times 3 \times 3 \times 3 \times 3 \times 3 = 2187\), which is not equal to 343.
- **B. \(7^3\)**: \(7^3 = 7 \times 7 \times 7 = 343\), which matches the given number.
- **C. \(7^{49}\)**: This is an extremely large number and not equal to 343.
- **D. \(294^{49}\)**: This is also an extremely large number and not equal to 343.

The correct answer is **B. \(7^3\)**.
