Cho \(A=\frac{1}{2}.\frac{3}{4}.\frac{5}{6}.....\frac{99}{100}\)
CMR: \(\frac{1}{15}< A< \frac{1}{10}\)
Cho A = \(\frac{1}{2}.\frac{3}{4}.\frac{5}{6}......\frac{99}{100}\)
CMR :\(\frac{1}{15}\) < A
Cho A=\(\frac{1}{2}.\frac{3}{4}.\frac{5}{6}.\frac{99}{100}\)
CMR \(\frac{1}{15}\)bé hơn A bé hơn \(\frac{1}{10}\)
Làm nhanh giùm mình!
Cho A = \(\frac{1}{2}.\frac{3}{4}.\frac{5}{6}.........\frac{99}{100}\)
CMR : \(\frac{1}{15}\) < A
Cho A=\(\frac{1}{2}.\frac{3}{4}.\frac{5}{6}...\frac{99}{100}\)Chứng minh rằng:\(\frac{1}{15}< A< \frac{1}{10}\)
cho \(M=\frac{1}{2}.\frac{3}{4}.\frac{5}{6}....\frac{99}{100};N=\frac{2}{3}.\frac{4}{5}.\frac{6}{7}....\frac{100}{101}\)
a/ so sánh M và N
b/ tính M nhân N
c/ CMR : M < 1 / 10
Cho \(A=\frac{1}{2}.\frac{3}{4}.\frac{5}{6}.....\frac{99}{100}\)
CTR: \(\frac{1}{15}< A< \frac{1}{10}\)
\(M=\frac{1}{2}.\frac{3}{4}.\frac{5}{6}....\frac{99}{100}\). cmr 1/15 < M <1/10
Cho \(A=\frac{1}{2}.\frac{3}{4}.\frac{5}{6}...\frac{99}{100}\)
Chứng minh rằng 1/15 < A < 1/10
