Can base be negative

A negative base (or negative radix) may be used to construct a non-standard positional numeral system. Like other place-value systems, each position holds multiples of the appropriate power of the system's base; but that base is negative—that is to say, the base b is equal to −r for some natural number r (r ≥ 2). Negative-base systems can accommodate all the same numbers as standard place-value syste… WebWhile negative pH values are most certainly possible (see all of the other answers), there is a practical element to the idea that the pH scale goes from 0-14. Most commercial pH meters, the ones used in educational settings (and many commercial settings) have a significant amount of error as you move to very high and very low pH.

WebNote that R 2 is not always the square of anything, so it can have a negative value without violating any rules of math. R 2 is negative only when the chosen model does not follow the trend of the data, so fits worse than a horizontal line. Example: fit data to a linear regression model constrained so that the Y intercept must equal 1500. WebIndeed we define: a n = ∏ k = 1 n a And even if a is negative this has a meaning. Then we extend the definition for n ∈ Z and for n ∈ Q. When we are to define to n ∈ R we define it as: a x = e x ln a That's fine, but ln is a function defined on R + so that if we try to compute ( − 5) π we'll get into trouble because this would be:
