All numbers have cube roots (not necessarily integral cube roots) so every prime has cube roots.
Some calculators don't have cube roots, so you could use X to the power of 1/root. x^(1/root). The cube root of 64 equals 4 because 4*4*4 (or 4^3) gives 64. You can reverse these powers by reciprocating the exponent: 64^(1/3) = 4
They are 3 and 5 respectively
