Quais s\u00e3o os n\u00fameros do conjunto \\(A\\) que s\u00e3o irracionais?<\/p>\n
\\[A = \\left\\{ { – 8;\\; – \\sqrt {27} ;\\;\\frac{3}{7};\\;\\pi ;\\;\\sqrt {81} } \\right\\}\\]<\/p>\n
[A]<\/strong> \\({ – \\sqrt {27} }\\) e \\(\\pi \\)<\/p>\n

S\u00e3o racionais os seguintes n\u00fameros: \\({ – 8}\\), \\({\\frac{3}{7}}\\) e \\(\\sqrt {81} = 9\\).<\/p>\n
S\u00e3o irracionais os dois restantes n\u00fameros: \\({ – \\sqrt {27} }\\) e \\(\\pi \\).<\/p>\n
Portanto, a op\u00e7\u00e3o correta \u00e9 [A]<\/strong> \\({ – \\sqrt {27} }\\) e \\(\\pi \\).<\/p>\n
