\frac{x^{6}}{x^{8}}
To multiply powers of the same base, add their exponents. Add 5 and 1 to get 6.
\frac{1}{x^{2}}
Rewrite x^{8} as x^{6}x^{2}. Cancel out x^{6} in both numerator and denominator.
\frac{\mathrm{d}}{\mathrm{d}x}(\frac{x}{1}x^{5-8})
To divide powers of the same base, subtract the denominator's exponent from the numerator's exponent.
\frac{\mathrm{d}}{\mathrm{d}x}(xx^{-3})
Do the arithmetic.
-3xx^{-3-1}
The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is 0. The derivative of ax^{n} is nax^{n-1}.
\left(-3x\right)x^{-4}
Do the arithmetic.
