Answer 1

836. а)

$frac{3 times 1 times 4}{5 times 2 times 9} = frac{12}{90}$

б)

$frac{1 times 2 times 3 times 4}{2 times 3 times 4 times 5} = frac{24}{120} = frac{2}{60} = frac{1}{30}$

в)

$frac{4 times 35 times 3}{7 times 36 times 5} = frac{1 times 5 times 3}{1 times 9 times 5} = frac{15}{45} = frac{1}{3}$

г)

$frac{4 times 10 times 15}{5 times 27 times 16} = frac{1 times 2 times 15}{1 times 8 times 16} = frac{30}{128}$

837. а)

$(frac{2}{9}) {}^{2} = frac{4}{81}$

б)

$( frac{2}{3} ) {}^{3} = frac{8}{27}$

в)

$( frac{1}{4} ) {}^{3 } = frac{1}{64}$

г)

$frac{4}{3} {}^{2} = frac{16}{9} = 1 times frac{7}{9}$

д)

$frac{1}{5} {}^{3} = frac{1}{125}$

е)

$frac{3}{7} {}^{2} = frac{9}{49}$
