10 (or e) to the power of x range from zero to infinity.

Lets try the extreme cases:

10^infinity = infinity

10^0 = 1

10^-infinity = 1/infinity = 0

Is there a negative answer on logarithm?

Logarithms of numbers less than one are negative. For example, the logarithm of 1/2 will be negative.

What is logarithm of log -2?

There is no answer. Logarithms operate only on non-negative numbers. * * * * * Actually, logarithms are not defined for 0 either, so they operate only on positive numbers.

What is the log of -123?

Within the real numbers, logarithms of zero and negative numbers are not defined. If you are interested in calculating logarithms within the complex number system, the Wikipedia article on "logarithm" has the necessary formulae. In this case, you can obtain the logarithm of a negative number, but not of zero.

Why log you is unmdefined?

I am not quite sure what you mean with "log you"; the log is calculated for numbers. The following logarithms are undefined: For real numbers: the logarithm of zero and of negative numbers is undefined. For complex numbers: the logarithm of zero is undefined.

Are logarithms rational numbers?

They may be, but usually they are not.

Why negative numbers don't have logarithim?

The logarithmic function is not defined for zero or negative numbers. Logarithms are the inverse of the exponential function for a positive base. Any exponent of a positive base must be positive. So the range of any exponential function is the positive real line. Consequently the domain of the the inverse function - the logarithm - is the positive real line. That is, logarithms are not defined for zero or negative numbers. (Wait until you get to complex analysis, though!)
