How do I handle square root within square root questions? I don't have a sample question, though. Can anyone help me?

Hello, consider a root to be a power to a rational exponent. Example: $\displaystyle \sqrt{\sqrt{a}}=\left( a^{\frac{1}{2}} \right)^\frac{1}{2}=a^{\frac{1}{4}}$ In general: $\displaystyle \sqrt[x]{\sqrt[y]{a}}=a^{\frac{1}{x} \cdot \frac{1}{y}}=\sqrt[x \cdot y]{a}$ EB
Thank you so much. I had no idea that such formulas existed. Now it all makes sense. Thanks!
