Output of "Solve" as a list

   Asking for "Solve" command won't give a list , for example:

In[23]:=
data = Solve[x\^2 == 4, x]
Out[23]=
{{x -> -2}, {x -> 2}}

But if I want to use the output , for example :

In[24]:=
data^3
Out[24]=
(  ( x -> (-2) }^3, ( (x -> {2) }^3  } .

the software dosen't consider x-> ... , as a number ,
but literally as "x->..." , so when asking data^3 it gives
(x->...)^3 .

Can anyone help me ? , thank you .
