Răspuns:
[tex]a = \frac{15}{16}[/tex]
[tex]b = \frac{10}{16}[/tex]
[tex]a > b[/tex]
Explicație pas cu pas:
[tex]a = (-\frac{3}{4} )^{2} + \frac{3}{8} =[/tex] [tex]\frac{9}{16} + \frac{3}{8} = \frac{9 + 3x2}{16} = \frac{9+6}{16} = \frac{15}{16}[/tex]
[tex]b =\frac{5}{8}x0.4 +\frac{5}{8} x 0.6 = \frac{5}{8} x (0.4 + 0.6) = \frac{5}{8} x 1 = \frac{5}{8}[/tex]
[tex]a = \frac{15}{16}[/tex]
[tex]b = \frac{5}{8} = \frac{10}{16}[/tex]
[tex]= > a > b[/tex]
