so sanh 199^3^voi 200^2
A=1/2.3/4......199/200 so sanh A voi 1/10 va 1/20
\(A=\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+...+\frac{1}{200}\);\(B=\frac{1}{199}+\frac{2}{198}+\frac{3}{197}+...+\frac{198}{2}+\frac{199}{1}\)Tinh \(\frac{A}{B}\)Giup minh voi
So Sánh 196/197+197/198 và 198/199+199/197
Cho A=1/2+1/3+1/4+...+1/199+1/200
B=1/199+2/198+3/197+...+198/2+199/1
Tính A : B
cho A = 1/199+2/198+3197+...+198/2+199/1.Chứng minh A = 200.(1/2+1/3+...+1/200)
so sanh
2^300 va 3^201
2^500 va 2^198
tính a /b
A=1/2+1/3+1/4+..+1/200
B=1/199+2/198+3/197+...+198/2+199/1
Tính B=\(\frac{1}{199}+\frac{2}{198}+\frac{3}{197}+....+\frac{198}{2}+\frac{199}{1}\)
