Question

tính hợp lí :

3737 x 43 - 4343 x 7 / 2 + 4 + 6 + ... + 100

 

Answer 1

\(\frac{3737.43-4343.7}{2+4+6+...+100}\)

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

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

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

Ta có : Tử số bằng 0 \(\Rightarrow\) phân số trên bằng 0

\(=0\)

Answer 2

\(\frac{3737.43-4343.7}{2+4+6+....+100}\)

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

\(=\frac{37.4343-4343.37}{2+4+6+....+100}\\ =\frac{0}{2+4+6+...+100}\\ =0\)
