Answer 1

Olá !

Resolução :

Podemos utilizar o método de aproximação de Taylor ( Cálculo 2)

$\mathsf{\sqrt{N}\approx\dfrac{N + B}{2\sqrt{B}}} \\\\\\ \mathsf{\sqrt{77}\approx\dfrac{77 + 81}{2\sqrt{81}}} \\\\\\ \mathsf{\sqrt{77}\approx\dfrac{158}{2\cdot9}} \\\\\\ \mathsf{\sqrt{77}\approx\dfrac{158}{18}} \\\\\\ \mathsf{\sqrt{77}\approx\ 8,7}$

Resposta :

$\mathsf{\sqrt{77}\approx\ 8,7}$
