What does simplest radical form mean?

• Break it down, using factors, pair them up, then leave non factors inside of radical.

• Break it down, then leave pairs on the inside and move non factors to outside of the radical.

• Square root it and round the decimal to the tenths.

• Keep and shove.

"Perfect Squares" are numbers that can be square rooted evenly, with no decimals.

• True

• False
