Answer 1

Explicație pas cu pas:

$- \sqrt{9} = - 3$

$\frac{91}{7} = 13$

$1 \frac{2}{3} = \frac{5}{3}$

$\sqrt{6.25} = \sqrt{ \frac{625}{100} } = \frac{25}{10} = 2.5$

=>

$A = \Big\{ - 1,5 ; 0; \sqrt{2} ; - 2; 0,(3); - 3; \pi; 13; \frac{3}{4} ; \frac{5}{3} ; 2,5\Big\}$

$B = \Big\{0; 13\Big\}$

$C = \Big\{0; - 2; - 3; 13\Big\}$

$D = \Big\{ - 1,5 ; 0 ; - 2; 0,(3); - 3; 13; \frac{3}{4} ; \frac{5}{3} ; 2,5\Big\}$

$E = \Big\{\sqrt{2}; \pi\Big\}$
