You can put this solution on YOUR website! To solve this problem, remember this - A LOGARITHM IS AN EXPONENT.
The base is this case is assumed to be 10. The logarithm is given as
something between 1.465 and 1.483. So, you can rewrite this as:
Given the possible answers, you can pick the correct one without evaluating anything. First, you know it is not zero, since your base is 10 and you are raising it to some numer. Also, you know it is not -30, since again, you are raising +10 to some number. Hence, by the process of elimination, your answer is 30.
Good Luck,
