Expanding logarithmic expressions in exercise, use the properties of logarithms to rewrite the expression as the sum, difference, or multiple of logarithms.
in x^2/x^2 + 1

.

For values of x>0, it can be rewritten as

Step-by-step explanation:

For the expression:

We can apply this logarithmical property:

Then,

If we assume values of x > 0 (non negative values for x), then the expression could be rewritten as follows:

, since

We have to remember that domain (all possible values x) for logarithmic function is for all x > 0, or mathematically expressed as:

Domain:

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
