Parenthesis first
11+4=15
division second
15/3=5
what is the square root of 64? 8!
8x5=40
Answer is 40
We are technically FOILing this out... with a power of 3.
(x+y)(x+y)(x+y)
So we can first factor out the first two "x+y"s.
![( x^{2} +2xy + y^{2} )](https://tex.z-dn.net/?f=%28%20x%5E%7B2%7D%20%2B2xy%20%2B%20y%5E%7B2%7D%20%29)
, multiplied by the last "x+y".
![x^{3} +3 x^{2} y +3x y^{2} + y^{3}](https://tex.z-dn.net/?f=%20x%5E%7B3%7D%20%2B3%20x%5E%7B2%7D%20y%20%2B3x%20y%5E%7B2%7D%20%2B%20y%5E%7B3%7D%20)
Coefficients are the number that comes
in front of a variable. In this case, 1 comes in front of
![x^{3}](https://tex.z-dn.net/?f=%20%20x%5E%7B3%7D%20)
, 3 comes in front of
![x^{2} y](https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20y)
, 3 comes in front of
![x y^{2}](https://tex.z-dn.net/?f=x%20y%5E%7B2%7D%20)
, and 1 comes in front of
![y^{3}](https://tex.z-dn.net/?f=%20y%5E%7B3%7D%20)
.
Thus: 1, 3, 3, 1.
Answer Choice A
Perceent means parts out of 100
