Answer:
ln(c) = d
Step-by-step explanation:
There are two types of logarithm:
- Common Logarithm
- Natural Logarithm
Common Logarithm is a logarithm with any base with real positive numbers other than e.
Here are some examples of what are common logarithm:
[tex]\displaystyle \large{\log_3 9}\\\displaystyle \large{\log_{\frac{1}{2} 2}[/tex]
Natural Logarithm is a logarithm with a ‘e’ base only. You may notice that the answer you put in has a “e” base, that’s a natural logarithm.
It’s not wrong to answer as a [tex]\displaystyle \large{\log_e c = d}[/tex] but the form is not commonly used. The natural logarithm has its own special form which is [tex]\displaystyle \large{\ln}[/tex], the “ln” simply means the logarithm base e.
Here’s the comparison of writing ln and log base e:
[tex]\displaystyle \large{\ln 2 = \log_e 2}\\\displaystyle \large{\ln 10 = \log_e 10}\\\displaystyle \large{\ln e = \log_e e \to 1}[/tex]
Therefore, your answer should be in “ln” form rather log base e.
Hence, the answer should be: [tex]\displaystyle \large{\ln (c) = d}[/tex]
Hope this helps! Let me know if you have any questions.
