Log -3 equals?

There is no answer - it is an error: negative numbers do not have logarithms. The log if a number tells to what power the (positive) base must be raised to get the number. Raising any positive number to any power will never result in a negative number, so it is an error to try and take the log of a negative number.


What is -log equivalent to?

The negative log of a number is the log of the number's reciprocal ('1' divided by the number).

How is it possible to find the negative log explain?

Logs are defined only for positive numbers so the log of a negative number does not exist.


How do you find antilog of a negative number using a log table?

Well, isn't that just a happy little question! To find the antilog of a negative number using a log table, you can start by taking the absolute value of the negative number to make it positive. Then, look up the positive number in the log table to find its corresponding antilog. Remember, there are no mistakes in math, just happy little accidents!


How do you calculate - log 0.5?

The logarithm of a number less than 1 is negative. Therefore, -log 0.5 is the negative logarithm of 0.5 which is equal to -0.301.


Is it possible for a logarithm to equal a negative number?

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.


How do you see log of a negative number?

The logarithm of a negative number is undefined in the realm of real numbers. This is because logarithmic functions are defined only for positive real numbers. However, in the context of complex numbers, the logarithm can be defined for negative numbers using the formula ( \log(-x) = \log(x) + i\pi ), where ( i ) is the imaginary unit. This allows for a complex representation of logarithms of negative values.


What is gernal value of log y?

Log(y) can be any number, positive or negative, no limits. It all depends on the value of 'y'.


How does decibels work?

To calculate the number of decibels that power-level-'A' is greater than power-level-'B',-- Divide 'A' by 'B'-- Take the 'log' of the quotient-- Multiply the 'log' by 10 .If the result is negative, then 'A' is that many decibels lower than 'B'.


Why does calculators display an error when log 0 is typed?

Because the log of zero is "negative infinity", and the calculator display is too narrow to display that number.


Which phases of a typical bacterial growth curve illustrates a log change in cell number. Oviously log or growth phase is logarithmic. Is the death phase a negative log change?

The log phase of a bacterial growth curve represents exponential growth in cell number. It is followed by the stationary phase, where cell growth stabilizes. The death phase shows a decrease in cell number, but it may not necessarily follow a negative logarithmic trend.
