Correct Answer
A. 1,8751Explanation
Since log 75 is equal to log (3 x 5 x 5), we can use the properties of logarithms to simplify the expression. By using the property log (a x b) = log a + log b, we can rewrite log 75 as log 3 + log 5 + log 5. Substituting the given values of log 3 and log 5, we get 0.477 + 0.699 + 0.699 = 1.8751. Therefore, the correct answer is 1.8751.Rate this question:
