Obviously, n is 3 digits, and the first digit is 1.

3 5 mantissa 3

0 5 mantissa 0

4 5 mantissa 4

7 5 mantissa 7

Therefore, the mantissa of N y 5 is 3+0+7+4 = 14, Y = 4, and n can be expressed as 1x4.

Because the largest of the four numbers is 133, and X >: 3,

In order to determine what X is, we can do experiments with squares.

13+ 1 1 & gt； 14

13^2+ 1 1^2 = 290 & gt； 14^2 = 196

13^3+ 1 1^3 = 3528 & gt； 14^3 = 2744

13^4+ 1 1^4 = 43202 & gt； 14^4 = 384 16

13^5+ 1 1^5 = 532344 & lt； 14^5 = 537824

So x = 4.

n = 144
