1. **State the problem:** Rewrite the radical expressions with positive exponents. 2. **Recall the rule:** A radical expression like $\sqrt[n]{x}$ can be written as $x^{\frac{1}{n}}$. To rewrite with positive exponents, express radicals as fractional exponents and simplify. 3. **Rewrite each expression:** - $\sqrt{6 e t t e r g}$ means $\sqrt{6 e t^2 e r g}$, which is $(6 e t^2 e r g)^{\frac{1}{2}}$. - $y^{\frac{1}{2}}$ is already a positive fractional exponent. - $\sqrt{n - -}$ is ambiguous, but assuming it means $\sqrt{n}$, rewrite as $n^{\frac{1}{2}}$. 4. **Final rewritten expressions with positive exponents:** - $(6 e t^2 e r g)^{\frac{1}{2}}$ - $y^{\frac{1}{2}}$ - $n^{\frac{1}{2}}$ Note: The other expressions in the message are either incomplete or unclear for rewriting radicals with positive exponents.
