Step 2.2.1

Factor $2$ out of $- 14$ .

$x^{2 (- 7) \frac{1}{6}}$

Step 2.2.2

Factor $2$ out of $6$ .

$x^{2 \cdot - 7 \frac{1}{2 \cdot 3}}$

Step 2.2.3

Cancel the common factor.

$x^{2 \cdot - 7 \frac{1}{2 \cdot 3}}$

Step 2.2.4

Rewrite the expression.

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

Step 2.3

Combine $- 7$ and $\frac{1}{3}$ .

$x^{\frac{- 7}{3}}$

Step 2.4

Move the negative in front of the fraction.

$x^{- \frac{7}{3}}$

Step 3

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{1}{x^{\frac{7}{3}}}$
