Answer:

Step-by-step explanation:
Assuming the problem is asking you to factor out the formula, it can be done easily by finding a common number with the two givens.
4 goes into both 12 and 16 evenly, so we will use this to factor. But that's not all, we have the n-variable to worry about.
Look at the n-variable exponents in the problem, take the highest power that can go be subtracted from both and use that. We have a
and
. Since 5 can't go into 3, we must use 3 to factor.
Our factoring variable will therefore be
. Now, use this to simply divide and get the answer:

So how did we get this? For the whole numbers, we have to divide: (12/4, 16/4). Next, we have to minus the exponents since we are dividing.
When dividing the 12 and 4, minus the
and
to get
. Get rid of the
term for the 16 and leave the 4. And there's your answer!

Answer:
c
Step-by-step explanation:
To convert the improper fraction

into a mixed number, you first want to
divide the numerator (1000)
by the denominator (859)
:

The
quotient, which is 1, will be your whole number part of your mixed number. The
remainder, 141, will become the numerator of the fraction part of your mixed number. The
original denominator of your improper fraction, 859, is still the denominator of your mixed number. So your mixed number form of your improper fraction is:
Your answer is
