Technical Documentation: Radical to Rational Exponent Translation Rules

You are working as an assistant technical writer for a scientific software company. Your team is compiling a documentation guide for a new symbolic computation tool that only accepts formulas in rational exponent form.

To help users transition from legacy radical formulas, write a brief explanatory guide that states and explains the rules for converting each of the following three types of radical expressions into rational exponent form:

A radical expression with an implied index of 2 and a compound radicand, using $\sqrt{10m}$ as your example.
A radical expression with an explicit index greater than 2 and a compound radicand, using $\sqrt[5]{3n}$ as your example.
A radical expression with an outside coefficient, an explicit index, and a compound radicand, using ${}3\sqrt[4]{6y}$ as your example.

In your response, be sure to:

State the general equivalence formula $a^{\frac{1}{n}} = \sqrt[n]{a}$ (or $\sqrt[n]{a} = a^{\frac{1}{n}}$ ) that serves as the basis for these conversions.
Explain how to determine the exponent's denominator when the index is implied (not visible) versus when it is explicit.
Explain why parentheses must be used around the compound radicands (like $10m $and \$ 3n$) when writing the exponential form, and what would happen if they were omitted.
Explain how to handle an outside coefficient (like the 3 in ${}3\sqrt[4]{6y}$ ) during the conversion.
Provide the final converted rational exponent expression for all three examples: $\sqrt{10m}$ , $\sqrt[5]{3n}$ , and ${}3\sqrt[4]{6y}$ .
