To convert a number into its logarithmic form, you can calculate either the common logarithm (base 10) or the natural logarithm (base e).
For the common logarithm (base 10):
\[ \log_{10}(0.0072) \]
By calculating this value, you find:
\[ \log_{10}(0.0072) \approx -2.140 \]
This means that \(0.0072\) is equivalent to \(10^{-2.140}\).
If you have access to a logarithm table, you would typically find the logarithm value for numbers within a certain range, and then use interpolation if your number falls between two values in that table. Since the value you mentioned is a small number, it would likely yield a negative logarithm.
If you need the natural logarithm (base \(e\)), it would be:
\[ \ln(0.0072) \approx -4.927 \]
Make sure to specify which logarithm you are interested in (common or natural) and refer to the appropriate values or tables.
