Ta có : \(\frac{2014}{2014+1975}< \frac{2014}{1963+2014};\frac{1975}{1963+1975}< 1\)

Vậy: \(A< \frac{2014}{1963+2014}+\frac{1963}{1963+2014}+1\)

\(A< \frac{2014+1963}{1963+2014}+1\)

\(A< 2\)

Ta có: \(\frac{2014}{2014+1975}< \frac{2014}{1963+2014}\)

Và \(\frac{1975}{1963+1975}< 1\)

Nên \(A< \frac{2014}{1963+2014}+\frac{1963}{1963+2014}+1\)

\(A< \frac{2014+1963}{1963+2014}+1\)

\(\Rightarrow A< 1+1\)     \(\Rightarrow A< 2\)

Vậy:  \(A< 2\)

Good luck !!! Rất vui vì giúp đc bạn bạn <3

        A  = B vi suy ra duoc 1968 - 1963 = 5

                                         ma : 1963 - 1958 = 5

5 =5 nen A =B

t mink nha

\(\dfrac{25}{27};\dfrac{51}{53};\dfrac{47}{49};\dfrac{103}{105};\dfrac{2009}{2011};\dfrac{1963}{1963};\)

25/27,47/49,51/53,103/105,2009/2011,1963/1963.

bn cho thiếu đề rồi

a= 3857295

b=3857296

a ) 1963 x 1965 la :

 1963 x 1965 = 3857295

b ) 1964 x 1964 la :

1964 x 1964 = 3857295

D/S : a) 385729

         b) 385729

( hai kết quả giống nhau )

Sửa đề:
\(\left(\dfrac{1975}{1976}+\dfrac{2010}{2011}+\dfrac{1963}{1968}\right)\times\left(\dfrac{1}{3}-\dfrac{1}{4}-\dfrac{1}{12}\right)\)
\(=\left(\dfrac{1975}{1976}+\dfrac{2010}{2011}+\dfrac{1963}{1968}\right)\times\dfrac{4-3-1}{12}\)
\(=\left(\dfrac{1975}{1976}+\dfrac{2010}{2011}+\dfrac{1963}{1968}\right)\times\dfrac{0}{12}\)
\(=0\)
