b)

$( - \frac{ 5}{7} ) {}^{2} = ( - \frac{5 {}^{2} }{7 {}^{2} } ) = ( - \frac{25}{49} )$

c)

$( - \frac{1}{3} ) {}^{3} = ( - \frac{1 {}^{3} }{3 {}^{3} } ) = ( - \frac{1}{27})$

d)

$( \frac{5}{7}) {}^{0} =( - \frac{5 {}^{0} }{7 {}^{0} }) = 1$

e)

$( - \frac{2}{5} ) {}^{1} = ( - \frac{2 {}^{1} }{5 {}^{1} }) = - \frac{1}{5}$
