E= 50 – 4/13 + 2/15 + – 2/17 / 100 – 8/13 + 4/15 – 4/17 25/08/2021 Bởi Daisy E= 50 – 4/13 + 2/15 + – 2/17 / 100 – 8/13 + 4/15 – 4/17
$\frac{50-\frac{4}{13}+\frac{2}{15}-\frac{2}{17}}{100-\frac{8}{13}+\frac{4}{15}-\frac{4}{17}}$ $=\frac{2\left(25-\frac{2}{13}+\frac{1}{15}-\frac{1}{17}\right)}{4\left(25-\frac{2}{13}+\frac{1}{15}-\frac{1}{17}\right)}$ $=\frac{2}{4}=\frac{1}{2}$ Bình luận

E=( 50 – 4/13 + 2/15 – 2/17 ) / ( 100 – 8/13 + 4/15 – 4/17 )
E= 50/100 – 4/13 / 8/13 + 2/15 / 4/15 – 2/17 / 4/17
E= 1/2 – 1/2 + 1/2 – 1/2
E= 0
