Cho M =1/2-3/4+5/6 -7/8+...+197/198-199/200
Và N= 1/51+1/52+...+1/100
Tính M:N
cho M=1/2-3/4+5/6-7/8+...+197/198-199/200 N=1/51+1/52+1/53+...+1/100 tính M/N
M=1/2-3/4+5/6-7/8+...+197/198-199/200
N=1/51+1/52+1/53+...+1/100
Tính M : N
CHO P = 1/2 -3/4 + 5/6 - 7/8 +................+ 197/198 - 199/200
Q = 1/51 +1/52 +...................+1/100
TÍNH Q :P
Cho \(M=\frac{1}{2}-\frac{3}{4}+\frac{5}{6}-\frac{7}{8}+...+\frac{197}{198}-\frac{199}{200}\) và \(N=\frac{1}{51}+\frac{1}{52}+\frac{1}{53}+....+\frac{1}{100}\)
Tính N : M
2/3*x-(1/2-3/4+5/6-7/8+...+197/198-199/200)=1/51+1/52+1/53+...+1/99+1/100
Tìm x
Cho M=\(\frac{1}{2}-\frac{3}{4}+\frac{5}{6}-\frac{7}{8}+...+\frac{197}{198}-\frac{199}{200}\)
N=\(\frac{1}{51}+\frac{1}{52}+\frac{1}{53}+...+\frac{1}{100}\)
Tính N:M
tìm N:M biết
\(M=\frac{1}{2}-\frac{3}{4}+\frac{5}{6}-\frac{7}{8}+...+\frac{197}{198}-\frac{199}{200}\)
\(N=\frac{1}{51}+\frac{1}{52}+...+\frac{1}{100}\)
