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

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

Take out the constants

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

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

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

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

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

Use the negative power rule : ${x}^{-a}=\frac{1}{{x}^{a}}
$

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

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

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

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

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

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

Artemon [7]

Answer:

Step-by-step explanation:

The cost of the x mangoes was ...

c = 10(x/4)

The revenue from the sale of mangoes was ...

r = 20(x-5)/5

The profit is the difference between revenue and cost:

10 = r - c = 20(x -5)/5 -10(x/4) = 1.5x -20 . . . . substitute and simplify

30 = 1.5x . . . . . add 20

20 = x . . . . . . . .divide by 1.5

The trader bought 20 mangoes.

_____

Check

He paid 20(10/4) = 50 naira. He sold the 15 good mangoes for 20/5(15) = 60 naira, so made a 10 naira profit.
