Answer:

$\frac{x^5+y^5}{x+y}=x^4-x^3y+x^2y^2-xy^3+y^4$

Step-by-step explanation:

Given the expression

$\left(x^5+y^5\right)\div \left(x+y\right)$

$\mathrm{Apply\:factoring\:rule:\:}x^n+y^n=\left(x+y\right)\left(x^{n-1}-x^{n-2}y+\:\dots \:-\:xy^{n-2}\:+\:y^{n-1}\right)\:\quad \quad \mathrm{n\:is\:odd}$

$x^5+y^5=\left(x+y\right)\left(x^4-x^3y+x^2y^2-xy^3+y^4\right)$

$=\frac{\left(x+y\right)\left(x^4-x^3y+x^2y^2-xy^3+y^4\right)}{x+y}$

Cancel the common factor: x+y

$=x^4-x^3y+x^2y^2-xy^3+y^4$

Thus,

$\frac{x^5+y^5}{x+y}=x^4-x^3y+x^2y^2-xy^3+y^4$

Step-by-step explanation:

1. 11,437 is less than 11,473. 3, the tens place, is less than 7

2. Find the LCD of 5/8 and 1/3. It is 24, 5/8 * 3/3 = 15/24, 1/3 * 8/8 = 8/24

15/24 + 8/24 = 23/24

3. Divide 3902 by 8, 3902/8 = 487.75, As a mixed number, that is 487 3/4

4. 725 * 41 = 29,725

5. Add 2 to 17, 19, 21, 23, and 25. Add 4 to 19, 23, 27, 31, 35, and 39
