Question

Fie multimeaA A{-1;5;0;√2;-2;0;(3);√9.

Answer 1

Explicație pas cu pas:

$A = \Big\{-1; 5; 0; \sqrt{2} ; -2; 0,(3); \sqrt{9} \Big\}$

$0,(3) = \frac{3}{9} = \frac{1}{3}$

$\sqrt{9} = \sqrt{ {3}^{2} } = 3$

$A = \Big\{-1; 5; 0; \sqrt{2} ; -2; \frac{1}{3} ; 3 \Big\}$

$\iff A = \Big\{-2; -1; 0; \frac{1}{3} ; \sqrt{2} ; 3; 5 \Big\}$
