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}&#10; 

(4x^1^-^8)^-^3 

(4x^-^7)^-^3 

Use the n<span>egative power rule : </span>{x}^{-a}=\frac{1}{{x}^{a}}&#10; 

\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}
