1) Simplifique as expressões, reduzindo a uma só potência: a) (−20)12 . (−20)17 . (−20)4
b) (+6)10 . ( +6)100 . (+6)20 . (+6)3
c) (+9)11 ÷ (+9)7
d) [()14 ÷ ()5. ()] ÷ [()6 ÷ ()3]
e) [(−4)8. (−4)5] . [ (−4)7 ÷ (−4)2]

Answer 1

Resposta:

a) $2^{4}$ *3 * 17

Explicação passo-a-passo:

a) (−20)12 . (−20)17 . (−20)4

  [ (−20)12 . (−20)17 . (−20)4 ] : -20

   12 * 17 *4 = ($2^{2}$ *3) * 17* ($2^{2}$)

     $2^{4}$ *3 * 17
