the two-digit number whose cube root is the square root of the sum of its digits


THe cube root of 27 is 3.


Only two possible answers; 27 or 64

Looks fairly obvious.


2+7 = 9. Sqrt 9 = 3 and (27)^1/3 = 3. check.

6+ 4 = 10. sqrt 10 = 3+ and (64)^1/3 = 4
doesn't check. or have I missed something.
