If is completely simplified to , where a, b, c, and d represent integer exponents, what is the value of c?

First of all, thanks for properly formatting the question!! That's something you don't see so often..

Anyway, the first thing to do is split the fraction in two fractions, using the rule

So, your expression becomes

Now, for each of the fractions we can simplify the numeric part and the exponents, using the rule

.

We have

So, the whole expression becomes

which means that the four coefficients are

So, in particular, c=2

well what you have to do is divide 84 by 6 so theanswer

step-by-step explanation:

84 divided by 6 = 14

and that lightbulb changing party must be freaking lit!

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
