Is the answer key wrong? or it's me?
ok, so im reviewing for a math test and the following question is from the practice final exam. Rationalize the denominator in the example:
2 x 3
after multiplying both the numeration and denominator by the conjugate of the denominator I got
2 x + 6 x 3
But, in the answer key the answer is
2 x 6 x 3
The problem looks quite simple, but I'm not sure what is the answer.

2 x 3 = 2 x 3 x 3 x 3 = 2 ( x 3 ) ( x 3 ) 2 = 2 x 6 x 3

The answer key is right (it's you): You must have multiplied numerator by x 3 , not x + 3

Clarification about percentage calculus
Why if we want to know what percentage of 16 is 4 we do
4/16
and not
16/4
?
4/16 gives you the answer, because it's equal to 0.25, that is equal to 25%, while 16/4 doesn't (I guess); but I don't understand the logic. It seems more natural to me to do 16/4, because if I want to know the percentage I would split the 16 by 4 to know how many parts does the 4 create (in my logic the number of parts created define the percentage). So if I try to do 16/4 I get 4, but then I don't know how to go on to get 25%. Maybe there's a way to obtain the result in the way I'm proposing but I don't know it.
I hope my question doesn't sound stupid, but this is one of the many basic things that I'm lacking in math to fully understand its logic.

Order approximation for rational polynomial
I have this fraction: ( 12 a 3 ) d 3 + ( 4 w a 3 16 a 2 ) d 2 + ( 5 w a 2 8 a ) d a 2 w 2 + 2 a w 1 ( 12 w a 4 + 12 a 3 ) d 3 + ( 4 a 4 w 2 20 a 3 w + 16 a 2 ) d 2 + ( 4 a 3 w 2 11 a 2 w + 7 a ) d + a 2 w 2 2 a w + 1
How can I approximate it so it may be written as a function of increasing order of d? As in f ( d ) + f ( d 2 ) + H . O . T
I have tried using Taylor series but that is centered around a point (which I don't want). I am looking into Pade approximation but am utterly confused. Can someone help me?
