Question

Determine o valor da expressão abaixo:

Answer 1

Resposta:

$-\dfrac{1}{15}$

Explicação passo-a-passo:

$\left(\dfrac{1}{2}+\dfrac{1}{3}\right)\cdot(-5)^{-1}+\sqrt{0,01}\to\\\\\\\dfrac{3+2}{6}\cdot\left(-\dfrac{1}{5}\right)+\sqrt{\dfrac{1}{100}}\to\\\\\\\dfrac{\not5}{6}\cdot\left(-\dfrac{1}{\not5}\right)+\dfrac{1}{10}\to\\\\\\-\dfrac{1}{6}+\dfrac{1}{10}\to\dfrac{-5+3}{30}=\\\\\\=-\dfrac{2}{30}\,\,\text{ou}\,\,-\dfrac{1}{15}\,\,\text{(resposta final)}$

É isso!! :)
