for 2 and 3, the answer is 70
2^70 is only the 2nd power of 2 to have all 10 digits

for powers of 4 and 5, the answer is 34

Funny tangent :

2^64 is the lowest power where if you represent the number in bases:3,5,7,9 or 11 (2 is trivial), all the possible digits for base b can be found in the base b representation of number.
