Question

15 – Calcule as potências: a) 0 18 b) ( - 1 ) 7 c) ( - 3 ) 4 d) - 3 4 e) ( + 5 ) 0 f) ( - 7 ) 0 g) ( - 13 ) 2 h) ( - 10 ) 2 i) – 10 2

Answer 1

Resposta:

$a)0^{18} =0$

$b)(-1)^{7} =(-1)\times(-1)\times(-1)\times(-1)\times(-1)\times(-1)\times(-1)=-1$

$c)(-3)^{4} =(-3)\times(-3)\times(-3)\times(-3)=81$

$d)-3^{4} =-3\times-3\times-3\times-3=-81$

$e)(+5)^{0} =1$

$f)(-7)^{0} =1$

$g)(-13)^{2} =(-13)\times(-13)=169$

$h)(-10)^{2} =(-10)\times(-10)=100$

$i)-10^{2} =-10\times-10=-100$
