So sánh giùm mik nha.
a) \(\frac{3}{-4}v\text{à}\frac{-1}{-4}\)
b) \(\frac{15}{17}v\text{à}\frac{25}{27}\)
c) \(\frac{-9}{6}v\text{à}\frac{6}{-4}\)
d) \(\frac{2000}{2001}+\frac{2001}{2002}v\text{à}\frac{2000+2001}{2001+2002}\)
Lm đc bài nào thì giải giúp mik vs nha.
SO SÁNH \(A=\frac{2000}{2001}+\frac{2001}{2002}v\text{à}B=\frac{2000+2001}{2001+2002}\)
so sánh các phân số :
a) \(\frac{18}{91}v\text{à}\frac{23}{114}\) b) \(\frac{21}{52}v\text{à}\frac{213}{523}\) c) \(\frac{1313}{9191}v\text{à}\frac{1111}{7373}\)
So sánh:
a)\(3^{200}v\text{à}2^{300}\)
b) \(71^{50}v\text{à}37^{75}\)
c) \(\frac{2016014}{2017015}v\text{à}\frac{2016016014}{2017017015}\)
\(\frac{25}{48}v\text{à}\frac{34}{69};\frac{62}{139}v\text{à}\frac{57}{141}\)So sánh phân số
help me now!!!!!
rút gọn rồi quy đồng mẫu các phân số sau và so sánh
\(\frac{5.6+5.7}{5.8+20}v\text{à}\frac{8.9-4.15}{12.7-180}\)
So sánh :
\(10^{30}v\text{à}2^{100}\)
\(5^{300}v\text{à}3^{453}\)
\(29^{12}v\text{à}18^{17}\)
so sánh
\(10^{30}v\text{à}2^{106}\)
\(333^{444}v\text{à}444^{333}\)
So sánh: A=1999/2000+2000/2001 và B=1999+2000/2000+2001
So sánh hai phân số sau:
A=\(\frac{1999^{2002}+1}{1999^{2001}+1}\)
và B=\(\frac{1999^{2001}+1}{1999^{2000}+1}\)
