List all integers less than 1,000,000 that are both perfect squares and perfect cubes.?

Answer 1

if it is a perfect square and a perfect cube then it is a power of 6

now (1000000)^(1/6) = 10

so the numbers are < 10^6

n^6 when n < 10 that is 1^6,2^6,3^6,4^6,5^6,6^6,7^6,8^6,9^6
or 1,64,729,... others can be numerically evaluated

Answer 2

Aside from 1, the answers are:

64, (4 cubed or 8 squared)
729 (9 cubed or 27 squared)
4,096 (16 cubed or 64 squared)
15,625 (25 cubed or 125 squared)
46,656 (36 cubed or 216 squared)
117,649 (49 cubed or 343 squared)
262,144 (64 cubed or 512 squared)
531,441 (81 cubed or 729 squared)
1,000,000 (100 cubed or 1,000 squared)
