Nested Radicals: When radicals are nested one within the other, the appropriate number of order-of-radical indicators must be used to show the depth of each inner radical.
If an inner radical has not index, the appropriate order-of-radical indicator must be placed before its radical sign. If an inner radical has an index, the appropriate order-of-radical indicator must be placed before the index-of-radical indicator.
The order-of-radical indicator used before an inner radicalmust also be used before its corresponding termination indicator. When more than one radical is complete at the same point, the radicals are terminated, beginning with the innermost radical.
