Answer 1

Answer:

$5^{0}$

Step-by-step explanation:

consider a=(-2/5)

we know that $a^{m}$*$a^{n}$=$a^{m+n}$

so $a^{-7}$X $a^{9}$=$a^{2}$

$a^{2}$/$a^{2}$=1

The result hence is $5^{0}$ since $5^{0}$=1

Answer 2

Answer:

Step-by-step explanation:

$[(\frac{-2}{5} )^{-7} * (\frac{-2}{5} )^{9} ] / (\frac{-2}{5} )^{2}$  

$[(\frac{-2}{5} )^{9-7} ] / (\frac{-2}{5} )^{2}$

$(\frac{-2}{5} )^{2} * (\frac{-5}{2} )^{2}$

$= \frac{4}{25} * \frac{25}{4} = 1$

∴ $Answer = 1^{5}$
