Finally, we'd divide both sides by 5. x= 2.678 . How Are Natural Logs Different From Other Logarithms? As a reminder, a logarithm is the opposite of a power. If you take the log of a number, you're undoing the exponent. The key difference between natural logs and other logarithms is the base being used. slow eater dog food bowlWebNov 16, 2024 · Okay, in this equation we’ve got three logarithms and we can only have two. So, we saw how to do this kind of work in a set of examples in the previous section so we just need to do the same thing here. It doesn’t really matter how we do this, but since one side already has one logarithm on it we might as well combine the logs on the other side. software engineer bootcamp near me
