Lesson 11-1B
Simplify other radicals
(cube roots, 4th roots, etc…)
Radical Expressions
Parts:All of it together is a radical expression
625 Radicand
Radical
Index – when invisible, it is a 2.
6253
- this number tells how many to group together
To simplify ANY radical….use the JAILBREAK method
1. Make a factor tree
2. Factors in groups that match the index can escape
3. Only one survives once they break out
4. Any factor not part of a group stays in

An invisible 2 told you that prisoners could escape in groups of 2 (but only one survives).
What would a 3 tell you? How about a 4?
