2. √200=
3. 6√128 =
4. 4√243 =
5. √28 - √125 + √63 - √80 =

Answer 1

1. √108 = √4.27
            = 2√27
2. √200 = √4.50
            = 2√50
3. 6√128 = 128/6
             = 21
4. 4√243 = 243/4
             = 61
5. √28 - √125 + √63 - √80 
  = √4.7 - √5.25 + √7.9 - √4.20
  = 2√7 - 5√5 + 3√7 - 2√20
  = 2√7 + 3√7 - 5√5 - 2√20
  = 5√7 - 5√5 - 2√20
