Giúp mik nha

tính tổng các hệ số của đa thức thu được sau khi khai trường kiến thức sau: (x^2 - 5x + 5)^2306

nó bằng

1/1x3+1/3x5+1/5x7+1/7x9+1/9x11+1/11x13+1/13x15

=1-1/3+1/3-1/5+1/5-1/7+1/7-1/9+1/9-1/11+1/11-1/13+1/13-1/15

loại đi thì còn
=1-1/15

=14/15

câu này dễ mà cũng hỏi là sao bạn ?

45 + 381 - 8 + 54 = 472

Ta có: 3311 và 4214 cùng chia hết cho số lớn nhất là 301

=>3311:301=11  => Tử số là 11

=> 4214:301=14=> Mẫu số là 14

=> Phân số sau khi rút gọn có tử 11, mẫu 14

=> Phân số đó là: 11/14

Chúc bạn học tốt !
