#### About 12 Maths Exercise 5.4

So far we have done the derivatives polynomials, rational numbers, trigonometric functions and tested the differentiability of modulus function, greatest integer function, etc. Now we have to deal with exponential and logarithm functions. So, we must know about the properties of log, which will be very useful for 12th Maths Exercise 5.5.

If any function is given as the sum of two exponential function, we can’t take log directly (This is the common mistake done by most of the students). We should differentiate the two functions separately and combine them to get the final answer.

##### Properties of log functions

1. log ab = log a = log b

2. log a/b = log a – log b

3. lag a^b = b log a

There is no addition formula in log function, means log (a + b) ≠ log a + log b, therefore we will different the two functions separately and add then to find the final answer.
