cho A =1/2 +1/3 +1/4 +.....+1/308+1/39
B = 308/1 +307/2 +.....+3/306 +2/307+1/308.Tính a+b
Cho A= 1/2+1/3+1/4+1/5+...+1/308+1/309
B=308/1+307/2+306/3+305/4+...+3/306+2/307+1/308
Tính A/B
A=1/2+1/3+1/4+...+1/308+1/309
B=308/1+307/2+306/3+...+3/306+2/307+1/308
Tính A/B.
Cho:
A=1/2+1/3+1/4+1/5+...+1/308+1/309
B=308/1+307/2+306/3+...+3/306+2/307+1/308
Tính A/B ? ( Có cách làm )
cho A=1/2+1/3+1/4+...+1/308+1/309
B=308/1+307/2+306/3+...+3/306+2/307+1/308
tim A/B
Cho A = 1/2 + 1/3 + 1/4 + 1/5 + ............ + 1/308 + 1/309
B = 308/1 + 307/2 + 306/3 + ................... + 3/306 + 2/207 + 1/308
Tính A/B
A=1/2+1/3+1/4+...+1/309
B=308/1+307/1+...+1/308
Tính A/B
\(A=\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+\frac{1}{5}+....+\frac{1}{308}+\frac{1}{309}\)
\(B=\frac{308}{1}+\frac{307}{2}+\frac{306}{3}+....+\frac{3}{306}+\frac{2}{307}+\frac{1}{308}\)
Tính\(\frac{\:A}{B}\)
Cho: \(A=\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+...+\frac{1}{307}+\frac{1}{308}+\frac{1}{309}\)
\(B=\frac{308}{1}+\frac{307}{2}+\frac{306}{3}+...+\frac{3}{306}+\frac{2}{307}+\frac{1}{308}\)
Tính \(\frac{A}{B}\)
