Question

Calcule a expressão numérica: (3/5)° + ( 5/6 - √4) ÷ [(1/2)¹ - 2²]

Answer 1

Resposta:

4/3

Explicação passo-a-passo:

${( \frac{3}{5}) }^{0} + ( \frac{5}{6} - \sqrt{4} ) \div ( {( \frac{1}{2} )}^{1} - {2}^{2} ) = \\ \\ 1 + ( \frac{5}{6} - 2) \div ( \frac{1}{2} - 4) = \\ \\ 1 + ( \frac{5 - (6 \times 2)}{6} ) \div ( \frac{1 - (2 \times 4)}{2} ) = \\ \\ 1 + ( \frac{5 - 12}{6} ) \div ( \frac{1 - 8}{2} ) = \\ \\ 1 + ( \frac{ - 7}{6} ) \div ( \frac{ - 7}{2} ) = \\ \\ 1 + ( \frac{ - 7}{6} ) \times ( \frac{ - 2}{7} ) = \\ \\ 1 + ( \frac{ - 1}{3} \times \frac{ - 1}{1} ) = \\ \\ 1 + \frac{1}{3} = \\ \\ \frac{3 + 1}{3} = \\ \\ \frac{4}{3}$
