Answer 1

1)

A)

$\frac{5}{4} .\frac{3}{5} .\frac{5}{4} .\frac{3}{5} =\\\\\frac{1}{4} .3.\frac{1}{4} .3=\\\\\frac{1}{4} .\frac{3}{1} .\frac{1}{4} .\frac{3}{1} =\\\\\frac{1.3.1.3}{4.1.4.1} =\frac{9}{16}$

B)

$\frac{2}{7} .\frac{2}{7} .\frac{5}{8} .\frac{2}{7} =\\\\\frac{1}{7} .\frac{2}{7} .\frac{5}{4} .\frac{2}{7} =\\\\\frac{1}{7}.\frac{1}{7} .\frac{5}{2} .\frac{2}{7} =\\\\\frac{1}{7} .\frac{1}{7} .5.\frac{1}{7} =\\\\\frac{1.1.5.1}{7.7.1.7} =\frac{5}{343}$

C)

$\frac{1}{4} .\frac{1}{4} .\frac{5}{4} .\frac{1}{4} =\\\\\frac{1.1.5.1}{4.4.4.4} = \frac{5}{256}$

D)

$\frac{2}{3} .\frac{2}{3} .\frac{2}{5} =\\\\\frac{2.2.2}{3.3.5} =\frac{8}{45}$

--------

2)

A)

$\frac{2}{7} .\frac{2}{7} .\frac{2}{7} = (\frac{2}{7} )^{3}$

B)

$\frac{2}{3} .\frac{2}{3} .\frac{2}{5} .\frac{2}{5} = (\frac{4}{15} )^{2}$

C)

D)

$\frac{5}{7} .\frac{5}{7} .\frac{5}{7} .\frac{5}{7} .\frac{5}{7} = (\frac{5}{7})^{5}$
