When what is the value of X, the formula √ x + 2 + 3 has the minimum value? What is the minimum value? If √ 20m is a positive integer, what is the minimum value of the positive integer m? If x is greater than or equal to - 3 and less than or equal to 2, try to simplify the absolute value of X-2 + √ (x + 3) ^ 2 + √ x ^ 2-10x + 25

three thousand four hundred and fifty-two

m. N are all positive integers 2007 / 2008

2007/2008=4014/4016
2008/2009=4016/4018
So n / M = 4015 / 4017

A positive integer n is 2008 times the sum of its numbers. The minimum value of n is______ ．

① If it is 4 digits, let the numbers on each digit be A1, A2, A3, A4, then A1 × 103 + A2 × 102 + a3 × 10 + A4 = 2008 (a1 + A2 + a3 + A4), and there is no solution after term shifting. ② if it is 5 digits, let the numbers on each digit be A1, A2, A3, A4, A5, then A1 × 104 + A2 × 103 + a3 × 102 + A4 × 10 + A5
