Answer 1

Răspuns:

$a = \frac{15}{16}$

$b = \frac{10}{16}$

$a > b$

Explicație pas cu pas:

$a = (-\frac{3}{4} )^{2} + \frac{3}{8} =$ $\frac{9}{16} + \frac{3}{8} = \frac{9 + 3x2}{16} = \frac{9+6}{16} = \frac{15}{16}$

$b =\frac{5}{8}x0.4 +\frac{5}{8} x 0.6 = \frac{5}{8} x (0.4 + 0.6) = \frac{5}{8} x 1 = \frac{5}{8}$

$a = \frac{15}{16}$

$b = \frac{5}{8} = \frac{10}{16}$

$= > a > b$
