Answer:

(2x + y)(4x² - 2xy + y²)

Step-by-step explanation:

8x³ + y³ ← is a sum of cubes and factors in general as

a³ + b³ = (a + b)(a² - ab + b²) , then

8x³ + y³

= (2x)³ + y³

= (2x + y)((2x)² - 2xy + y²) , that is

(2x + y)(4x² - 2xy + y²)

Answer:

$M(T)=1.1(7(8+T^{10})^{3})$ and $M(T)=1.1(7(8+22^{10})^{3})=1.44\time10^{41}$

Step-by-step explanation:

We have the next set of functions:

$L(T)=8+T^{10}$

$V(L)=7L^{3}$

$M(V)=1.1V$

We want to know M(T) then:

$M(V)=1.1V$ but we know that $V(L)=7L^{3}$ :

$M(L)=1.1(7L^{3})$ and we know that $L(T)=8+T^{10}$

$M(T)=1.1(7(8+T^{10})^{3})$

Finally using the value of 22º we have

$M(T)=1.1(7(8+22^{10})^{3})=1.44\time10^{41}$
