Roots take a fractional form, so the 8th root as a power is 1/8. The indices would multiply so:

x^3/8.

"cubed root of x squared" is "(cubed root of x) squared" = "cubed root of (x squared)"
(x^2)^(1/3) = x^(2 * 1/3) = (x^(1/3) )^2

So the exponent or power os 2/3.

Which of the following equations could be the result of using the comparison method to solve the system shown?

masya89 [10]

Answer:

6-2y=4y+8

since you show x through y

Answer:

The result that is obtained on comparing the system of equations in order to get the solution to the system of equations is:

6 -2y =4y + 8

Step-by-step explanation:

We are given a system of equations in term of variable x and y as follows:

x + 2y = 6 --------(1)

x - 4y = 8-------------(2)

From equation (1) we have the value of x in terms of y as:

x=6-2y

From equation (2) we have the value of x in terms of y as:

x=8+2y

Hence, on equation the above two values of 'x' we obtain:

6 - 2y = 4y + 8

HELP PLEASE! Im struggling

kondaur [170]

Answer:

c. $\dfrac{2}{3}$

Step-by-step explanation:

Let the common ratio be r.

$a_2 = \dfrac{2}{5}$

$a_3 = \dfrac{2}{5}r$

$a_4 = \dfrac{2}{5}r^2$

$a_5 = \dfrac{2}{5}r^3$

We are told that $a_5 = \dfrac{16}{135}$ .

$\dfrac{2}{5}r^3 = \dfrac{16}{135}$

$\dfrac{5}{2} \times \dfrac{2}{5}r^3 = \dfrac{5}{2} \times \dfrac{16}{135}$

$r^3 = \dfrac{8}{27}$

$r = \sqrt[3]{\dfrac{8}{27}}$

$r = \dfrac{2}{3}$

Answer: c. $\dfrac{2}{3}$

En el supermercado de Laura cortan cada barra de pan en 9 trozos iguales para hacer bocadillos y en 13 trozos iguales para hacer

GaryK [48]

Answer:

1/9 para un bocadillo y 1/13 para un montadito.

Step-by-step explanation:

Bocadillo:

9/9 es el pan entero (porque dividiendo 9 entre 9, te da 1, es decir, la unidad). Para hacer un bocadillo tienes que sacar uno de los trozos, que sería 1/9.

Con los montaditos es igual solo que en vez de dividir el pan en 9 trozos, lo divides en 13.
