Rút gọn : `1) (2929-101)/(2*1919+404)` `2) (2^3*3^2*35)/(2^4*3^2*21)` `-` Làm nốt hộ em ạ `!`

1)

$\frac{2929-101}{2 . 1919+404}$

= $\frac{29 . 101 -101}{2 . 19 . 101+4 . 101}$

= $\frac{( 29 - 1 ) . 101}{(2 . 19 + 4) . 101}$

= $\frac{28 . 101}{42 . 101}$

= $\frac{28}{42}$

= $\frac{2}{3}$

2)

$\frac{2^{3} . 3^{2} . 35}{2^{4}.3^{2}.21}$

= $\frac{2^{3} . 3^{2} . 5 . 7}{2^{4}.3^{2}. 3 . 7}$

= $\frac{2^{3} . 3^{2} . 5 . 7}{2^{3}. 2 .3^{2}. 3 . 7}$

= $\frac{5}{2.3}$

= $\frac{5}{6}$
