Simplify the cube root in simplest radical form.<br> 9x374<br> Please help

algol [13]

Answer:

D. $xy\sqrt[3]{9y}$

Step-by-step explanation:

$\sqrt[3]{9x^3y^4}$

$\sqrt[3]{9}\sqrt[3]{x^3}\sqrt[3]{y^4}$

The $\sqrt[3]{x^3}$ cancels out to become x:

$\sqrt[3]{9}x\sqrt[3]{y^4}$

Split the $y^4=y*y^3$

$\sqrt[3]{9}x\sqrt[3]{y^3}\sqrt[3]{y^1}$

$\sqrt[3]{y^3} =y$

$xy\sqrt[3]{9} \sqrt[3]{y}$

Put the cube root of y and cube root of 9 together:

$xy\sqrt[3]{9y}$

Solve by any method (graphing, substitution or linear combination)

Lostsunrise [7]

Answer:

b) (5, -3)

Step-by-step explanation:

The given equations are;

$y=x-8...(1)$

$2x+3y=1...(2)$

I prefer using substitution because of the first equation.

Put equation (1) into equation (2) to obtain;

$2x+3(x-8)=1$

We expand the parenthesis to obtain;

$2x+3x-24=1$

Group similar terms to get;

$2x+3x=1+24$

Simplify

$5x=25$

Divide through by 5;

$x=\frac{25}{5}$

$\Rightarrow x=5$

Put $x=5$ into equation (1) to get;

$y=5-8$

$\Rightarrow y=-3$

The solution is (5,-3).

The correct answer is B
