Question

Calcule o valor numérico da expressão com a = 64 e b = 36.

Answer 1

$\sf \frac{ \sqrt{64 + 36} }{ \sqrt{64} + \sqrt{36} } = \\ \\ \frac{ \sqrt{100} }{ \sqrt{64} + \sqrt{36} } \\ \\\sf \frac{ 10 }{ \sqrt{64} + \sqrt{36} } = \\ \\\sf \frac{10}{ 8 + \sqrt{36} } = \\ \\\sf \frac{10}{8 + 6} = \frac{10}{14} = \red{ \frac{5}{7}}$
