$$\bf \Large x^{-\frac{1}{7}}\cdot x^{-\frac{1}{6}}\implies x^{-\frac{1}{7}+-\frac{1}{6}\implies \frac{?}{LCD?}}$$

Okay, I think the answer is

Is that correct? (:

$$\bf \Large {x^{-\frac{1}{7}}\cdot x^{-\frac{1}{6}}\implies x^{-\frac{1}{7}+-\frac{1}{6}\implies \frac{-13}{42}}\implies \cfrac{1}{x^{\frac{13}{42}}}}$$
