The logarithm function is the inverse of the exponential function. Take the exponential function (base 10): y = 10x. The inverse of this is x = 10y. The function y = log(x) is used to define this inverse function.
First look at y = 10x. Any real value of x will yield a positive real value for y. If x = 0, then y = 1; if x < 0 (negative) then y is between 0 and 1 (it will never equal zero, though). A value of 10-99999 is very close to zero, but not quite there. There are no real values of x which will give a negative y value for y = 10x.
Now look at y = log(x) or x = 10y. No matter what real values for y, that we choose, x will always be a positive number, so a negative value of x in y = log(x) is not possible if you are limiting to real numbers.
It is possible with complex and imaginary numbers to take a log of a negative number, or to get a negative answer to y = 10x.
Log(y) can be any number, positive or negative, no limits. It all depends on the value of 'y'.
Value of log 0 is negative infinity (undefined). Because no power can give an answer of zero. it is in fact undefined but written as negative infinity for symbolizing. Otherwise undefined and infinity are two different things.
the log of a number, X, is equal to some value , N, and by definition 10 to the N power =X 10 to any power is always positive

No. The range of the exponential (antilog) function is the positive reals (unless you are dealing with the complex field).

Since the pH is defined as the negative log of the H+ concentration, one simply needs to take the negative log of 2.3x10^-9. This value = pH = 8.6

pH is the negative log of the activity of the hydrogen ion in an aqueous solution. A powder is not a solution.

It is the negative value of the 10-base logarithmof [positive real number](cf. mathematics)
Authorization number
the log of a number, X, is equal to some value , N, and by definition 10 to the N power =X 10 to any power is always positive
The value of log o is penis
The negative log of a number is the log of the number's reciprocal ('1' divided by the number).
