log10 equals 1

This log does not specify a base, so the base is 10. When the base is the same number as the number you are taking the log of, then the answer will be 1. Logs can be transformed into exponential equations. Log10 is the same thing as saying

`10^x = 10`

We know that `10^1 = 10`

so the answer is 1.

log 10 = 1

since the base of the logarithm here is 10 and the logarithmic rule states:  `log_a a = 1`

i.e., logarithmic of a (to the base a) is 1.

please note that the natural log (to the base e) is generally denoted as 'ln'.

Hope this helps.
