Answer:
A
Step-by-step explanation:
Apply Quotient of Powers
[tex] \frac{x {}^{y} }{x {}^{z} } = x {}^{y - z} [/tex]
In this questions terms,
[tex] \frac{a {}^{ \frac{1}{3} } }{a {}^{ \frac{1}{4} } } = a {}^{ \frac{1}{3} - \frac{1}{4} } [/tex]
[tex] \frac{4}{12} - \frac{3}{12} = \frac{1}{12} [/tex]
