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:

4 packs of water and 7 packs of candy bars

step-by-step explanation:

35x4=140

140/20=7
