Log10 1000 = ?
Correct answer: B. 3
- A. 0.3
- B. 3
- C. 1/3
- D. 3.3
Explanation
The definition of a logarithm states that if loga b = x, then a^x = b. In this question, log10 1000 = x means that 10^x = 1000. Since 1000 can be rewritten as 10^3, it follows that x must be 3, making Option B the correct answer. The other options are incorrect: 10^0.3 is approximately 2, not 1000; 10^(1/3) is approximately 2.15, not 1000; and 10^3.3 is approximately 1995.26, not 1000.
