O número 0,36 e igual a :

a) (1/6) elevado a 2
b) (3/6) elevado a 2
c) (6/3) elevado a 2
d) (10/6) elevado a menos 2

Answer 1

$\large\boxed{\boxed{\sf Oi,Camila}}\\\\\\\sf Resposta\to \left(\dfrac{10}{6}\right)^{-2}\\\\\\\sf Conta \to\\\\\\\displaystyle \left(\frac{10}{6}\right)^{-2}\\\\\\\sf \boxed{\boxed{\tt \star \ {Aplique\:as\:propriedades\:dos\:expoentes}:\quad \:a^{-b}=\frac{1}{a^b}}}\\\\\\\sf \left(\frac{10}{6}\right)^{-2}=\frac{1}{\left(\frac{10}{6}\right)^2}\\\\\\\sf =\frac{1}{\left(\dfrac{10}{6}\right)^2}\\\\\\\sf =\frac{1}{\dfrac{25}{9}}$

$\tt \large\boxed{\boxed{\tt \star \ {Aplicar\:as\:propriedades\:das\:fracoes}:\quad \frac{1}{\dfrac{b}{c}}=\frac{c}{b}}}\\\\\\\sf \to \boxed{\boxed{\boxed{\tt =\frac{9}{25}\to 0,36}}}$
