Explicație pas cu pas:
Folosind regula de mai sus:
13.
a) [(-2)^2]^4= [tex]x^{2*4} =x^{8}[/tex]=(-2)^8=256
b) 5^(1*0)=1
c) (-7)^(3*2)=(-7)^6=7^6
d) 13^0^1=1
e) (17^2)^3=17^6
f) [(-1)^5]^12=(-1)^(5*12)=(-1)^60=-1
14.
a) 17^2/(-17)^2= (17/-17)^2 =1
b) (-25/-5)^3=5^3=125
c) (-361/19)^2=(19)^2=361
d) (324/-18)^2= (-18)^2=324
e) (1331/-121)^3= (-11)^3= -1331
f) (123/-123)^15= (-1)^15= -1
