\(D=\frac{3737.43-4343.37}{2+4+6+...+100}\)

\(\Rightarrow D=\frac{37.101.43-4343.37}{2+4+6+...+100}\)

\(\Rightarrow D=\frac{37.4343-4343.37}{2+4+6+...+100}\)

\(\Rightarrow D=\frac{4343.\left(37-37\right)}{2+4+6+...+100}\)

\(\Rightarrow D=\frac{4343.0}{2+4+6+...+100}\)

\(\Rightarrow D=\frac{0}{2+4+6+...+100}\)

\(\Rightarrow D=0\)

Vậy D = 0

D=0

ngắn gọn

\(D=\frac{3737.43-4343.37}{2+4+6+...+100}\)

Biến đổi tử số ta có :

\(D_1=3737.43-4343.37\)

\(\Rightarrow D_1=37.101.43-4343.37\)

\(\Rightarrow D_1=\left(43.101\right).37-4343.37\)

\(\Rightarrow D_1=4343.37-4343.37\)

\(\Rightarrow D_1=4343\left(37-37\right)=4343.0=0\)

Thay vào , ta có :

\(\frac{0}{2+4+6+...+100}=0\div\left(2+4+6+...+100\right)=0\)

Vậy : D = 0

ta có 

3737 . 43 - 4343 . 37 = ( 3700 + 37) . 43 - (4300+43) . 37

= 3700 . 43 + 37 .43 - 4300 . 37 + 43 . 37

= 43 . 37 . ( 3700 . 43 - 4300 . 37)

= 1591 . (159100 - 159100)

= 1591 . 0

= 0

vậy \(\frac{3737.43-4343.37}{2+4+6+....+100}\)= 0

đap số 0

1 nha bạn

Chúc các bạn học giỏi

Tết vui vẻ nha

bằng 0 nhé =))))

B=\(\frac{3737.43-4343.37}{2+4+6+...+100}\)=\(\frac{101.37.43-101.43.37}{2+4+6+...+100}\)=\(\frac{101\left(37.43-43.37\right)}{2+4+6+...+100}\)=\(\frac{0}{2+4+6+...+100}\)=0

C=\(\frac{101+100+...+3+2+1}{101-100+...+3-2+1}\)

=\(\frac{\left(101+1\right).101:2}{\left(101-100\right)+...+\left(3-2\right)+1}\) (nhóm 2 số hạng ở MS thì sẽ có 51 nhóm và dư 1 số hang )

=\(\frac{102.101:2}{1+...+1+1}\) ( Ms có 51 số 1)

=\(\frac{51.101}{51}\)=101

D=\(\frac{3737.43-4343.37}{2+4+6+...+100}\)

= \(\frac{37.101.43-43.101.37}{2+4+6+..+100}\)

= \(\frac{0}{2+4+6+...+100}\)

=0

Tick mik nha, thks bạn

\(b=\frac{3737\cdot43-4343\cdot37}{2+4+6+...+100}=\frac{37\cdot101\cdot43-43\cdot101\cdot37}{2+4+6+...+100}=\frac{0}{2+4+6+...+100}=0\)

\(B=\frac{3737\cdot43-4343\cdot37}{2+4+6+...+100}=\frac{37\cdot101\cdot43-43\cdot101\cdot37}{2+4+6+...+100}=\frac{0}{2+4+6+...+100}=0\)

`(3737.43-4343.37)/(2+4+...+100)`

`= (101.37.43-101.43.37)/(2+4+...+100)`

`=0/(2+4+...+100) = 0`

\(\dfrac{3737.43-4343.37}{2+4+6+...+100}\) 

Gọi \(A=2+4+6+...+100\) 

Số số hạng: \(\left(100-2\right):2+1=50\) 

Tổng dạy: \(\left(2+100\right).50:2=2550\) 

Gọi \(B=3737.43-4343.37\) 

\(B=101.37.43-101.43.37=0\) 

\(\Rightarrow\dfrac{3737.43-4343.37}{2+4+6+...+100}=\dfrac{0}{2550}=0\)

\(D=\frac{3737.43-4343.37}{2+4+6+...+100}\)

\(D=\frac{37.101.43-43.101.37}{2+4+6+...+100}\)

\(D=\frac{37.\left(101.43-43.101\right)}{2+4+6+...+100}\)

\(D=\frac{37.0}{2+4+6+...+100}\)

\(D=\frac{0}{2+4+6+...+100}=0\)

Vậy \(D=0\)
