Answer:

-3

Step-by-step explanation:

We need to use the distributive property a couple times to expand the parentheses.

Remember that when expanding parentheses, we find the sum of the products of the outside term with each of the inside terms.

5(x - 4) = 5 * x + 5 * (-4) = 5x - 20

-(2x + 5) = -1 * 2x + -1 * 5 = -2x - 5

Now we have:

5x - 20 + 3x - 9x = 6 - 2x - 5 + 8x

Combine all the terms with x:

-x - 20 = 6x + 1

7x = -21

Divide by 7:

x = -21/7 = -3

The answer is thus -3.

The required value after simplification of the s = -16/3. None of these are correct.

Given that,
To simplify $[\frac{x^{2/3}x^{-1/2}}{x\sqrt{x^3}\sqrt[3]{x}}]^2$ and to find the value of s in $x^s$ .

<h3>What is simplification?</h3>

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.

Simplification,

$=[\frac{x^{2/3}x^{-1/2}}{x\sqrt{x^3}\sqrt[3]{x}}]^2\\= \frac{x^{4/3}x^{-1}}{x^2x^3*{x}^{2/3}}\\= \frac{x^{1/3}}{x^{17/3}}\\=x^{-16/3}$
Comparing with $x^S$
s = -16/3
