Answer 13

for every integer from 1 to 1000 there is an n^2 less than 1,000,000. Therefore, there are 1000 perfect squares

for every integer from 1 to 100 there is an n^3 less than 1,000,000. Therefore, there are 100 perfect cubes.

there are 10 perfect squares that are also perfect cubes. 1^6, 2^6, 3^6...to 10^6.
Thus there are 1000+100-10=1090 distinct numbers that are perfect squares and perfect cubes.
Thus there are 998910 numbers not perfect squares or cubes
