Kết quả là 2432902008176640000. Vậy có 4 chữ số 0 đứng cuối

thanh kiu nha

Từ trang 1 đến trang 9 cần sử dụng số chữ số là:

( 9 - 1 ) : 1 + 1 = 9 ( chữ số )

Từ trang 10 đến trang 99 cần sử dụng số chữ số là:

[ ( 99 - 10 ) : 1 + 1 ] × 2 = 180 ( chữ số )

Từ trang 100 đến trang 350 cần sử dụng số chữ số là:

[ ( 350 - 100 ) : 1 + 1 ] × 3 = 753 ( chữ số )

Tổng số chữ số phải sử dụng là:

9 + 180 + 753 = 942 chữ số

Đáp số: 942 chữ số
