Hỗn hợp khí (T) ở đktc gồm 2 hiđrocacbon mạch hở X, Y có cùng số nguyên tử cacbon. Lấy 0,448 lít (T) cho từ từ qua nước brom thấy có 4,8 gam brom phản ứng, không có khí thoát ra khỏi bình nước brom. Mặt khác, đốt cháy 0,448 lít hỗn hợp T thì thu được 1,76 gam CO₂. Cho 0,3 mol hỗn hợp (T) tác dụng với dung dịch AgNO₃/NH₃ (dư) thu được m gam kết tủa. Giá trị của m là

a) Số chia hết cho 6 <=> chia hết cho cả 2 và 3

5ⁿ luôn có tận cùng là 5 nên B=5+(...5)+(...5)+...+(...5)   {60 số hạng là số chẵn}

                                  => B có tận cùng là 0 chia hết cho 2.

Mọi số hạng trong B đều chia 3 dư 1 hoặc 2 nên tổng B chia hết cho (cái này bạn phải chứng minh kĩ hơn nha)

      Suy ra điều phải chứng tỏ.

1. I joined in a piano institute last year 
2. mosquito​es is the intermediate for disease 
 

Gọi bán kính hình tròn là r , diện tích htron ban đầu là: S _đầu = r x r x 3,14

Diện tích htron sau khi tăng là: S _sau  = 120% x r x 120% x r x 3,14 = 144% x r x r x 3,14 = 144% x S _đầu

vậy S _tăng = 44% x S _đầu = 56,54 

S _đầu = 56,54 x 100 : 44 = 128,5 cm vuông

Câu hỏi nói phân biệt hay sao bạn
