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

Page 12: Abcdefghijklmnopqrstvwxyz What do you make of this?

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?
