Question

3) A expressão (1/3) + (2/3)² - (4/2) tem por resultado?

(22/9)
(11/9)
(22/18)
(11/18)

Answer 1

O valor obtido na expressão numérica é:

${{\boxed{{\boxed{\blue{\boxed{\Large{\rm{\purple { b) \:\frac{11}{9} \: }}}}}}}}}}$

Montando a expressão:

$(\frac{1}{3}) \: + (\frac{x}{y} )^{2} \: - \:( \frac{4}{2} )\\\\\frac{1}{3} \: + \:\frac{4}{9} \: -\: \frac{4}{2} \\\\\frac{3}{9} \: + \frac{4}{9} \: - \frac{4}{2}\\\\\frac{3\: + \:4}{9} - \frac{4}{2} \\\\\frac{7}{9} -\frac{4}{2}\\\\ \frac{7}{9} -\: 2\\\\\frac{7}{9} - \frac{18}{9} \\\\\frac{7-18}{9} \\\\\dfrac{11}{9}$

Espero ter ajudado!!
