Answer and explanation
Correct answer: 343
When powers with the same base are multiplied, their exponents are added: \(7^2 \times 7^1 = 7^{2+1} = 7^3 = 343\). Therefore, 343 is correct. The value 49 is only \(7^2\), so it is not the product. Exam tip: add exponents when multiplying powers with the same base.
