Use a calculator to find the logarithm of the following: 0.0007

Step 1 ：The problem is asking for the logarithm of 0.0007. In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x. In the case of a calculator, it is common to use the base 10 (common logarithm) or base e (natural logarithm). The question does not specify which base to use, so we will use the common logarithm (base 10) for this calculation.

Step 2 ：Let's denote the number as \( num = 0.0007 \)

Step 3 ：Calculate the logarithm of the number: \( log_{num} = -3.154901959985743 \)

Step 4 ：This means that 10 raised to the power of -3.1549 is approximately 0.0007.

Step 5 ：Final Answer: The logarithm of 0.0007 is approximately \(\boxed{-3.1549}\)
