Respuesta:
[tex] \sqrt{ \frac{9}{4} } + {2}^{ - 2} + \frac{2}{3} - (1 - \frac{2}{3} )^{2} = [/tex]
[tex] \frac{3}{2} + \frac{1}{2 ^{2} } + \frac{2}{3} - ( \frac{1}{ 3} )^{2} = [/tex]
[tex]\frac{3}{2} + \frac{1}{4 } + \frac{2}{3} - \frac{1}{ 9} = \frac{83}{36} [/tex]
[tex] = \frac{83}{36} = 2.305[/tex]
