I have a small question what is this-

Cerrena [4.2K]

Answer:

Step-by-step explanation:

negative 5 is less then -3 is the statement. so saying that -3 is less than five, is false.

remember your number line.

-5_-4_-3_-2_-1_0_1_2_3_4_5_6

five sure is to the left of three, and saying that three is to the right of five is the exact same thing.

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}}
$

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

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

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

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

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

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