Step-by-step explanation:

8 = 2^3 . . . a perfect cube

16 = 4^2 . . . a perfect square

32 = 2^5 . . . neither a cube nor a square

64 = 2^6 = 4^3 = 8^2 . . . both a perfect cube and a perfect square

128 = 2^7 . . . neither a cube nor a square

I need the solution and the work for it... for each of the multiple choices.

Vlad1618 [11]

For this case we have the following equation:

$x ^ 3 = 375$

We must find the value of "x":

We apply cube root on both sides of the equation to eliminate the exponent:

$x = \sqrt [3] {375}$

We can write 375 as $5 ^ 3 * 3$

So:

$x = \sqrt [3] {5 ^ 3 * 3}\\x = 5 \sqrt [3] {3}$

Then, the correct options are:

$x = \sqrt [3] {375}\\x = 5 \sqrt [3] {3}$

Option A and B

{2x + 3y = 5}{ y= 5 x -4}

Natasha_Volkova [10]

Solve the system using substitutions:

$\begin{gathered} 2x+3y=5 \\ 2x+3(5x-4)=5 \\ 2x+15x-12=5 \\ 17x=5+12 \\ 17x=17 \\ x=\frac{17}{17} \\ x=1 \end{gathered}$

x has a value of 1. Use this value to find the value of y.

$\begin{gathered} y=5x-4 \\ y=5\cdot1-4 \\ y=5-4 \\ y=1 \end{gathered}$

y has a value of 1.

x=1

y=1
