Question

Dau coroana! Am nevoie repede!​

Answer 1

$\it \dfrac{91}{7}=13\in\mathbb{N};\ \ \ -\sqrt9=-3\in\mathbb{Z};\ \ \sqrt{6,25}=2,5\in\mathbb{Q}$

$\it B=\{0;\ \dfrac{91}{7}\}\\ \\ \\ C=\{-\sqrt9;\ \ -2;\ \ 0;\ \ \dfrac{91}{7}\}\\ \\ \\ D=\{-1,5;\ \ 0;\ \ -2;\ \ 0,(3);\ \ -\sqrt9;\ \ \dfrac{91}{7};\ \ \dfrac{3}{4};\ \ 1\dfrac{2}{3};\ \ \sqrt{6,25}\}$

$\it E=\{\sqrt2;\ \ \pi\}$
