-------- - -------=(-2³√2 )/5 - (-2³√3)/(³√2 + ³√3 )=
5 ³√2 - ³√-3 =

(-2/5 ³√2 ) - (-2³√3)(³√4 -³√6 + ³√9 )/(2 + 3 )=
(-2/5 ³√2 ) - (-2³√3)(³√4 -³√6 + ³√9 )/5=
(-2/5 ³√2 ) - (-2/5 ³√3)(³√4 -³√6 + ³√9 )= (-2/5 ³√2 ) [1-(³√4 -³√6 + ³√9 )]=
(-2/5 ³√2 ) [1-³√4 +³√6 - ³√9 ]= -2/5 ³√2 + 4/5 - -2/5 ³√12 + 2/5 ³√18 ]=
