Question

Alguém sabe?

Sendo A = [-8,3], B = [-16,0] e C = ]1,10], determine:
(A - B) ∩ C.

Answer 1

$\boxed{\begin{array}{l}\tt A=[-8,3]\implies A=\{x\in\mathbb{R}/-8\leqslant x\leqslant3\}\\\tt B=[-16,0]\implies B=\{x\in\mathbb{R}/-16\leqslant x\leqslant 0\}\\\tt C=~]1,10]\implies C=\{x\in\mathbb{R}/1<x\leqslant10\}\end{array}}$

$\Large\boxed{\begin{array}{l}\tt A-B=\{x\in\mathbb{R}/0\leqslant x\leqslant3\}\\\tt (A-B)\cap C=\{1<x\leqslant3\}\end{array}}$
