Answer 1

$a)( \frac{1}{4} )^{2} = \frac{1}{4} * \frac{1}{4} = \frac{1}{16}$

$b) (\frac{-7}{10})^2 = \frac{-7}{10} *\frac{-7}{10} = \frac{+49}{100}$

$c)( \frac{-1}{5} )^3= \frac{-1}{5} * \frac{-1}{5} * \frac{-1}{5} = \frac{-1}{125}$

$d)( \frac{-1}{12} )^5= \frac{-1}{12} * \frac{-1}{12} * \frac{-1}{12} * \frac{-1}{12} * \frac{-1}{12} = \frac{-1}{248832}$

$e)( \frac{7}{11} )^0=1$
