Question

Determine o número de subconjunto A={1,4,6}. Quais são eles?

Answer 1

Existem $2^3 = 8$ subconjuntos. São eles:

S = {{},{1},{4},{6},{1,4},{1,6},{4,6},{1,4,6}}

$S = \left\{\left\{\right\},\left\{1\right\},\left\{4\right\},\left\{6\right\},\left\{1,4\right\},\left\{1,6\right\},\left\{4,6\right\},\left\{1,4,6\right\}\right\}$
