Add or subtract terms wherever possible.

1. 2 cube root of 135 + cube root of 455

2.y cube root of 24 - cube root of 192xy^3

none of your numbers in the cube roots in either question can be "broken down" to produce like terms, so you cannot add or subtract them

eg. cuberoot(455) = cuberoot((5)(7)(13))
which gets you nowhere.
