rearrangement of digits of powers of 2

100 Views Asked by At

Which nontrivial powers can be obtained by rearrangement of digits of powers of 2 ?


source - own curiosity, as usual in such cases...


Here are 3 interesting cases I discovered:

  • powers of 3 -- obviously impossible (sum of digits).

  • powers of 4 -- trivial.

  • powers of 5 -- possible: $2^9=512\rightsquigarrow 125=5^3$.

  • powers of 6 -- obviously impossible.

  • powers of 7 -- possible: $2^{10}=1024\rightsquigarrow 2401=7^4$.

  • powers of 8 -- trivial.

  • powers of 9 -- obviously impossible.

  • powers of 10 -- obviously impossible.

  • powers of 11 -- ??

  • powers of 12 -- obviously impossible.

  • powers of 13 -- ??

  • powers of 14 -- possible: $2^{14}=16384\rightsquigarrow 38416=14^4$.

  • powers of 15 -- obviously impossible.

  • powers of 16 -- trivial.
