(In reply to Solution by Larry)

I have already clarified in Corrigendum, that the original intention  was " to determine all possible values of N<10^9  such that N is a perfect power....." However,  the problem was published with the text as;: "possible values of N <10...."

Any inadvertent  inconvenience caused due to the foregoing anomaly  is sincerely regretted 

Charliie has since clarified the reason why this has happened.

I tried to read  your N<10^7 solution, but was unsuccessful in my attempts.

Consequently,  I  am writing this with a request  to repeat your solution.
