Explicação passo-a-passo:

$\blue {{ _{\heartsuit} } \heartsuit_{\heartsuit} } \: \: \mathsf {OI, TUDO \: \: J\acute{O}IA \: ? \: \:\blue {{ _{\heartsuit} } \heartsuit_{\heartsuit} } }$

$\sf{a = \left\{ x \in\mathbb{N}\diagup \: x \geqslant 5 \right\}}\rightarrow \: \sf{a =\left\{5,6,7,8,9,10... \right\} }$

$\sf{b = \left\{ x \in\mathbb{N} \diagup \: x < 7\right\}}\rightarrow \: \sf{b = \left\{ ... \: 1,2,3,4,5,6\right\}}$

$\boxed{\red{ \sf{a \cap \: b = \left\{5,6 \right\}}}}$
