We can expand the logarithm of a product as a sum of logarithms:

Then using the change of base formula, we can derive the relationship

This immediately tells us that

Notice that none of
can be equal to 1. This is because

for any choice of
. This means we can safely do the following without worrying about division by 0.

so that

Similarly,

so that

So we end up with

###
Another way to do this:



Then

So we have

Answer:
A=πr2
THIS IS THE ANSWER
PLEASE MARK BRAINLIEST!!!!!
I think it represents where something is starting from, like something growing up (a chart with rising numbers)
we have

If c is the independent variable
then
p is the dependent variable
so
clear variable p

Divide by
both sides

Adds
both sides


Write the equation in function notation

therefore
the answer is
the equation in function notation is equal to 
To get a number as a percent of another, you divide and multiply by 100, so here you would have (13/52)*100=.25*100=25, making your answer 25%.
