Đề bài mình nghĩ là đúng, còn về cách làm thì bạn theo công thức " số lớn nhất thỏa mãn trừ đi số nhỏ nhất thỏa mãn, rồi chia cho khoảng cách giữa các số rồi cộng 1"

1000= \(3^6\) + 729

vậy có tất cả 6 thừa số 3.

10 tháng 9 2016

Các bạn có thể giải cụ thể hơn 1 chút nữa được ko?

4 tháng 2 2017

Vì số đó chia hết cho2,5 nên có c/s cuối là 0

Chia hết cho 3và 9 phải có tổng chia hết cho 3, 9

=> co tong la 9,18,..

Co tong la 9 ta co

90,180,...

90 ko chia het cho4

180 chia het cho 4

Suy ra so can tim la 180

Tk mk nha
