All numbers between 1000 and 2000, or anywhere else, can be expressed as a power of another number.
3000
√2000 ≅ 44.7 √3000 ≅ 54.8 The squares of 45 to 54 lie within the range 2000 to 3000. There are thus 10 perfect square numbers between 2000 and 3000.
The question presumably refers to, 'How many squares of integers are between 1000 and 2000?' √1000 = 31.6 : √2000 = 44.7 The answer is the squares of the integers 32 to 44 . There are thus 13 squares of integers in the specified number range. 322 = 1024 : 332 = 1089 : 342 = 1156 : 352 = 1225 : 362 = 1296 : 372 = 1369 : 382 = 1444 : 392 = 1521 : 402 = 1600 : 412 = 1681 : 422 = 1764 : 432 = 1849 : 442 = 1936

Do a search on Google, for "prime numbers" table, or "prime numbers" list, and you will surely find something.I cannot tell precisely without looking up a table or doing some longish calculus but as a gross estimatation there should be about this many prime numbers between 1000 and 2000:2000 / ln(2000) - 1000 / ln(1000) =~ 263 - 144 = 119Actual number of primes between 1000 and 2000 should be a little above 119(in the range [140, 160] i think)

Answer : In total there are 22 numbers.
√2000 ≅ 44.7 √3000 ≅ 54.8 The squares of 45 to 54 lie within the range 2000 to 3000. There are thus 10 perfect square numbers between 2000 and 3000.
They are 1024, 1125 and 1372.

1000 to 2999 inclusive so 2000 numbers.

They are all the 4 digit numbers starting with 1 and ending with 1, 3, 5, 7 or 9. Since there are 500 of them, I will not list them.
