Adding and Subtracting Like Radicals
To add or subtract higher-order roots, apply the same logic used for combining like terms or like square roots: add or subtract the numerical coefficients while leaving the radical factor untouched. This operation requires that the terms be like radicals, meaning they must have identical indices and identical radicands. For instance, because both terms are fourth roots with the radicand . If the radicals do not match initially, you should first simplify each one by extracting the largest perfect th power factor. Often, this simplification process will reveal hidden like radicals that can then be successfully combined.

Technical Documentation: Criteria for Like Radicals
Automated Formula Validation
A technical script is being designed to automatically validate algebraic expressions in a company's structural database. To identify 'like radicals' for formula simplification, the script must follow a specific verification protocol based on the formal definition. Arrange the following steps in the correct logical order the script must follow to confirm two radicals are 'like'.
