Evaluate the logarithmic expression log_2(64) + log_3(81).
Answer and explanation
Correct answer: D. 10
- Step 1: Evaluate log_2(64): since 2^6 = 64, log_2(64) = 6. Step 2. Evaluate log_3(81): since 3^4 = 81, log_3(81) = 4. Step 3. Sum the values: 6 + 4 = 10. Answer: 10. Why not the others: 8 results from using 4+4; 12 and 14 stem from multiplying or incorrect power identifications.
