so sánh : \(\dfrac{1}{35}\) và \(\dfrac{1000}{-35}\)
có : \(\dfrac{1000}{-35}\) = \(\dfrac{-1000}{35}\)
\(\Rightarrow\) \(1\) \(>\) (\(-1000\) )
\(\Rightarrow\) \(\dfrac{1}{35}\) \(< \) \(\dfrac{-1000}{35}\)
vậy : \(\dfrac{1}{35}\) < \(\dfrac{1000}{-35}\) hay \(\dfrac{1000}{-35}\) > \(\dfrac{1}{35}\)
so sanh : 1/3+1/31+1/35+1/37+1/47+1/53+1/61 va 1/2
so sanh
35x 54 - 19 va 53 x 35 +12
so sanh
a,2^160 va 4^120; b,2^91 va 5^35; c,A=2^0+2^1+2^2+...+2^12 va B=2^11
so sanh phan so a.-22/35 va -105 / 177
b. (3/8)5 va (5/243)3
Hay so sanh 2 bieu thuc;
c= 35x 53- 18 va D= 35+ 53x 34
so sanh
23/48 va 47/92
415/395 va 572/581
1999/2001 va 12/11
1/a+1 va 1/a-1
1993/1995 va 997/998
43/49 va 31/35
ko tinh gia tri cu thr hay so sanh bieu thuc
a)A=199x201 va B=200x200
b)C=35x53-8 va D=35+53x34
Bai 1: So sanh:
291 va 535
Bai 2: Tim x:
5x+2 =625
cac ban oi giup minh voi
so sanh 2 mu 91 va 5 mu 35 dang luy thua lop 6 nang cao
