Which equation justifies why 93-3√9?
Simora [160]

Considering the conversion from exponent to radical, the equation that justifies why the expression 9^{\frac{1}{3}} = \sqrt[3]{9} is correct is.

(9^{\frac{1}{3}})^{3} = 9^{\frac{3}{3}} = 9

<h3>How is the conversion from exponent to radical realized?</h3>

The conversion of rational exponents to radical notation is modeled by:

a^{\frac{n}{m}} = \sqrt[m]{a^n}

In this problem, the expression is:

9^{\frac{1}{3}} = \sqrt[3]{9}

And the equation that shows that this is correct is:

(9^{\frac{1}{3}})^{3} = 9^{\frac{3}{3}} = 9

Solve by using square roots. ​ 6x^2−27=39
Bingel [31]

Answer:

Simplifying

x = 11

Step-by-step explanation:

Simplifying

6x + -27 = 39

Reorder the terms:

-27 + 6x = 39

Solving

-27 + 6x = 39

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '27' to each side of the equation.

-27 + 27 + 6x = 39 + 27

Combine like terms: -27 + 27 = 0

0 + 6x = 39 + 27

6x = 39 + 27

Combine like terms: 39 + 27 = 66

6x = 66

Divide each side by '6'.

x = 11

Simplifying

x = 11

QUESTION 7<br> Solve for x.<br> (3x + 32)<br> (5x-8)<br> O a. 3<br> b. 12<br> O c. 20<br> O d. 19.5
Alchen [17]

Answer:

The answer is x = 20

Step-by-step explanation:

If you set both equations equal to each other and solve for x, you will get 20.

3x+32 = 5x-8        add 8 to both sides

3x+40 = 5x           subtract 3x from both sides

40 = 2x                 divide by 2 on both sides

20 = x
