Answer 1

Hola!

Respuesta:

$E =6$

Explicación paso a paso:

$E = \frac{ {3}^{2n + 2} + {3}^{2n + 1} }{{3}^{2n + 1} - {3}^{2n} } \\ \\ E = \: \frac{ {3}^{2n}. {3}^{2} + {3}^{2n} .3 }{ {3}^{2n} .3 - {3}^{2n} } \\ \\ E = \frac{ {3}^{2n} ( {3}^{2} + 3)}{ {3}^{2n} (3 - 1)} \\ simplificamos : {3}^{2n} \\ \\ E = \frac{( {3}^{2} + 3) }{3 - 1} \\ \\ E = \frac{9 + 3}{2} \\ \\ E = \frac{12}{2} \\ \\ E =6$
