  1. POTENCIAÇÃO

  2. Definição Apotênciandeumnúmeroéoproduto de n fatores destenúmero: an ondenZ. = a. a.a.....a , n fatores expoente base

  3. Exemplo 23 =2.2 .2=8 a) 34 =3.3 .3.3=81 b) (-5)3=(- 5).(-5).(-5)=-125 c) 61 =6 d) (-8)2=(-8).(-8)=64 e)

  4. Regrasda potenciação Qualquer um. base real n,elevada a zero, éigual a n0 =1 Qualquer mesma. base real n,elevada a um,éigualaela n1 =n

  5. Exercício Calculeas potências: .2.2.2.2.2=128 1) 27 35 =2.2 a) =3.3.3.3.3=243 b) (-4)3 (-2)6 =(-4).(-4).(-4)=- 64 2).(-2) c) d) =(- 2).(-2).(-2).(- .(-2)=64 5-1 =1 e) 5 = -4 1 4 6 =6.6.6.6=1296 f) 6 1
