Question

Se consideră multimea T={-1/3;3:-3;√3;1/3;0,3;-3,(3)}. Efectuați T u (intors) N; T u (intors) Q:T u (intors) R; T-Q;T-Z;T-R

Answer 1

   
[tex]\displaystyle \bf \\ T=\left\{- \frac{1}{3};~3;~-3;~ \sqrt{3} ;~ \frac{1}{3};~0,3;~-3,\!\!(3)\right\}\\\\\\ T\cap R = T~~~\text{deoarece }~~T\subset R\\\\ T-Q = \Big\{ \sqrt{3} \Big\}\\\\ T-Z = \left\{- \frac{1}{3};~ \sqrt{3} ;~ \frac{1}{3};~0,3;~-3,\!\!(3)\right\} \\\\ T-R=\O~~~\text{deoarece }~~T\subset R[/tex]
