  4. a1=a (−b)1=−b x0=1 ●Arvu esimene aste võrdub alati tema endaga. ●Mis tahes arvu astendamiselnulliga on alati tulemuseks null.

  5. (−3)3=(−3)⋅(−3)⋅(−3)=−27 (−3)4=(−3)⋅(−3)⋅(−3)⋅(−3)=81 Negatiivse arvu aste on positiivne, kui astendaja on paarisarv. Kui astendaja on paaritu, siis aste on negatiivne.

  6. 2 (3 5) =3 5⋅3 5⋅3 5=9 5=9 25 32 5=3 5 Murdude astendamisel tuleb murd alati panna sulgudesse.

  7. (−4)4=256 −44=−256 −(2 3) 4 =−16 81 Samuti tuleb lisada sulud ka negatiivsetele arvudele.
