\(y=\frac{16.29-32}{16.37+32}=\frac{9}{13}\)

vậy y = \(\frac{9}{13}\)

t i ck nha!! 6546576876876976

= 29/37

29/37 ai k mk mk k gấp đôi

\(=\dfrac{16\cdot30-30-16}{16\cdot37+16\cdot2}=\dfrac{30\left(16-1\right)-16}{16\cdot39}\)

\(=\dfrac{30\cdot15-16}{16\cdot39}=\dfrac{434}{16\cdot39}=\dfrac{217}{312}\)

a) \(\frac{3^2.2^4}{8.3^2}=\frac{3^2.2^4}{2^3.3^2}=2\)

b)\(\frac{84.45}{49.54}=\frac{2^2.7.3^3.5}{7^2.2.3^3}=\frac{10}{7}\)

c) \(\frac{36.10.21}{2^3.63.35}=\frac{2^3.3^3.5.7}{2^3.3^2.5.7^2}=\frac{3}{7}\)

d) \(\frac{16.29-32}{16.37+32}=\frac{16.29-16.2}{16.37+2.16}=\frac{16.\left(29-2\right)}{16.\left(37+2\right)}=\frac{27}{39}=\frac{9}{13}\)

3².2⁴

= 3².2².2²

= 6².2²

= 12²

Cms ơn nha=)

Ta có:

\(\begin{array}{l}\frac{{24}}{{108}} = \frac{{24:12}}{{108:12}} = \frac{2}{9};\\\frac{{80}}{{32}} = \frac{{80:16}}{{32:16}} = \frac{5}{2}\end{array}\)

= 2/7 

= 33/8 

nha bn nguyen tuan anh

\(\frac{48}{168}\cdot\frac{132}{32}=\frac{2^4\cdot3}{2^3\cdot3\cdot7}\cdot\frac{2^2\cdot3\cdot11}{2^5}=\frac{2\cdot1}{1\cdot1\cdot7}\cdot\frac{1\cdot3\cdot11}{2^3}=\frac{33}{28}\)
