Question

determine o valor numérico dessa expressão algébrica ​

Answer 1

Resposta:

$\sqrt{8^{2}+8.10/9 } \\\sqrt{64+8.10/9} \\\sqrt{64+80/9} \\\sqrt{144/9} \\\sqrt{16} \\4$

Answer 2

$\sqrt{ \frac{ {8}^{2} + 8 \times 10}{9} } = \sqrt{ \frac{64 + 80}{ {3}^{2} } } = \\ \sqrt{ \frac{144}{ {3}^{2} } } = \sqrt{ \frac{ {12}^{2} }{ {3}^{2} } } = \frac{12}{3} = 4$
