Javier simplified the expression below. Find and describe the three mistakes he made.

OverLord2011 [107]

$( \dfrac{20x}{5x^8})^-^3$

<span>Take out the constants
</span>
$( \dfrac{20}{5} * \dfrac{x}{x^8} ) ^-^3$

$(4*\dfrac{x}{x^8} ) ^-^3$

Use the rule : $\frac{{x}^{a}}{{x}^{b}}={x}^{a-b}
$

$(4x^1^-^8)^-^3$

$(4x^-^7)^-^3$

Use the n<span>egative power rule : </span> ${x}^{-a}=\frac{1}{{x}^{a}}
$

$\frac{1}{4(x^-^7)}^-^3$

$\frac{1}{4^3(x^-^7)}^-^3$

$\dfrac{1}{64x^-^2^1}$

$\dfrac{1}{64* \dfrac{1}{x^2^1}}$

$\dfrac{1}{64 \dfrac{}{x^2^1}}$

$= \dfrac{x^2^1}{64}$

this is the question pls help me 4 friends evenly divided up an n-slice pizza. One of the friends, Harris, ate 1 fewer slice tha

Pani-rosa [81]

Answer:

$\frac{n}{4}-1$

Step-by-step explanation:

If we have a pizza that has $n$ slices and we want to split it between 4 friends, then each friend will get $\frac{n}{4}$ slices.

Now, Harris is one of those friends so he receives $\frac{n}{4}$ slices, but he eats one less than he receives. Therefore, we subtract one from this expression to get our final answer of $\frac{n}{4}-1$ .

Hope this helped!
