urgenteee

Answer 1

Resposta:

$\boxed{\mathtt{Quatro}}$

Explicação passo a passo:

Olá!

$\\ \displaystyle \mathtt{f(x) = \log_2 (x + 11)} \\\\ \mathtt{f(5) = \log_2 (5 + 11)} \\\\ \mathtt{f(5) = \log_2 16} \\\\ \mathtt{f(5) = \log_2 2^4} \\\\ \mathtt{f(5) = 4 \cdot \log_2 2} \\\\ \mathtt{f(5) = 4 \cdot 1} \\\\ \boxed{\boxed{\mathtt{f(5) = 4}}}$
