Explicație pas cu pas:
(-3)^5 = (-3)^4*(-3)^1 = (-3)^2*(-3)^3 = (-3)^5*(-3)^0
_________________
(+7)^3 = (+7)^0*(+7)^3 = (+7)^2*(+7)^1 = (+7)^3*(+7)^0
_________________
(-2)^4 = (-2)^7 : (-2)^3 = (-2)^5 : (-2)^1 = (-2)^6 : (-2)^2
__________________
(-5)^7 = (-5)^10 : (-5)^3 = (-5)^8 : (-5)^1 = (-5)^7 : (-5)^0

(-4)^20 = [(-4)^4]^5 = [(-4)^5]^4
__________________
(-6)^10 = [(-6)^2]^5 = [(-6)^5]^2
