103và 2100
Ta có:1030=(103)10=100010
2100=(210)10=102410
Vì 1000<1024 nên 1030<2100
5300 và 3453
Ta có:5300=(52)150=25150
3453=(33)151=27151=27.27150
Vì 25 < 27.27 nên 5300<3453
nhớ k ch mình nhé
So sánh:
a)\(3^{200}v\text{à}2^{300}\)
b) \(71^{50}v\text{à}37^{75}\)
c) \(\frac{2016014}{2017015}v\text{à}\frac{2016016014}{2017017015}\)
so sánh
\(10^{30}v\text{à}2^{106}\)
\(333^{444}v\text{à}444^{333}\)
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=\(\frac{17^{18}+1}{17^{19}+1}v\text{à}B=\frac{17^{17}+1}{17^{18}+1}\)
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.
\(\frac{25}{48}v\text{à}\frac{34}{69};\frac{62}{139}v\text{à}\frac{57}{141}\)So sánh phân số
help me now!!!!!
Bài 1: So sánh
\(\frac{429}{639}v\text{à}\frac{219}{333}\)
\(\frac{10^{15}+1}{10^{16}+1}v\text{à}\frac{10^{16}+1}{10^{17}+1}\)
\(A=\frac{20^{10}+1}{20^{10}-1}v\text{à}B=\frac{20^{10}-1}{20^{10}-3}Sos\text{á}nhAv\text{à}B\)
So sánh với n thuộc N*
\(\frac{n+1}{n+2}v\text{à}\text{ }\frac{n}{n-3}\)
