The natural logarithm (ln) is used when you have log base e
Yes. The logarithm of 1 is zero; the logarithm of any number less than one is negative. For example, in base 10, log(0.1) = -1, log(0.01) = -2, log(0.001) = -3, etc.
determination of log table value
log(36,200) = 4.558709 (rounded)log[log(36,200)] = 0.658842 (rounded)
That is the same as log xy.
