  8. Way to remember factorial answers...
    The #! x the previous answer.
  9. i.e. 6! = 5! = (120) x 6 = 720
  10. √8 =
    2√2
  11. √27 =
    3√3
  12. 1/2√8 =
    82
  13. a√x =
    x1/a
  14. 642/3=
    (3√64)2 = 42 = 16
  15. If there is a question with 1 radical, process is ...
    ex: √(x+3) + 7 = 20
    • Isolate the radical to one side ->
    • √(x+3) = 13
  16. If there is a question with 2 radicals, process is...
    ex: √(x+3) + √(x+2) = 0
    • Place one radical on each side.
    • √(x+3) = - √(x+2)
