Odpowiedź:
a )
= [tex]a^{6 - (-15)} = a^{21}[/tex]
b) = [tex]x^{-9 - (-91)} = x^{82}[/tex]
c) = [tex]y^{100 - ( - 90)} = y^{190}[/tex]
d ) = [tex]k^{-20 - (-15)} = k^{-5}[/tex]
e ) = [tex]m^{-19 - (-25)} = m^{15}[/tex]
f ) = [tex]z^{20 - (-10)} = z^{30}[/tex]
Szczegółowe wyjaśnienie:
[tex]\frac{a^m}{a^n} = a^{m - n}[/tex]
==========
