Step-by-step solution

To solve this problem, we must simplify the expression 3436\frac{\sqrt[4]{3}}{\sqrt[6]{3}}. We will follow these steps:

  • Step 1: Convert roots to exponents.
    34\sqrt[4]{3} is equivalent to 3143^{\frac{1}{4}}, and 36\sqrt[6]{3} is equivalent to 3163^{\frac{1}{6}}.
  • Step 2: Apply the quotient of powers formula.
    Using the property aman=amn\frac{a^m}{a^n} = a^{m-n}, we have: 314316=31416 \frac{3^{\frac{1}{4}}}{3^{\frac{1}{6}}} = 3^{\frac{1}{4} - \frac{1}{6}}
  • Step 3: Perform the subtraction of the exponents.
    To subtract the fractions 14\frac{1}{4} and 16\frac{1}{6}, find a common denominator. The least common multiple of 4 and 6 is 12, so: 14=312,16=212 \frac{1}{4} = \frac{3}{12}, \quad \frac{1}{6} = \frac{2}{12} Thus, 1416=312212=112 \frac{1}{4} - \frac{1}{6} = \frac{3}{12} - \frac{2}{12} = \frac{1}{12}
  • Step 4: Simplify the result.
    Thus, we have: 31416=3112 3^{\frac{1}{4} - \frac{1}{6}} = 3^{\frac{1}{12}}

Hence, the simplified form of the given expression is 3112 3^{\frac{1}{12}} .
