[tex] {( - 1)}^{2017} + {( - 1)}^{2018} = { - 1}^{2017} + {( - 1)}^{2018} = - 1 + ( { - 1}^{2018}) = - 1 + {1}^{2018} = - 1 + 1 = 0[/tex]
Orice numar la putere impara daca e cu minus ramane lafel
[tex] ({ - 1})^{2017} = - 1[/tex]
[tex] ({ - 1})^{2018} = 1[/tex]
=> -1+1 = 0
[tex] ({ - 1})^{2017} = - 1[/tex]
[tex] ({ - 1})^{2018} = 1[/tex]
=> -1+1 = 0
