1.Sa se calculeze: 17supra3[15supra90+radical din25 supra 16]

Answer 1

$\frac{17}{3} ( \frac{15}{90} + \frac{ \sqrt{25} }{16} )= \frac{17}{3} ( \frac{15}{90} + \frac{5}{16} )= \frac{255}{270} + \frac{85}{48} = \frac{2040}{2160} + \frac{3825}{2160} = \\ = \frac{5865}{2160} ^{(5} = \frac{1173}{432} ^{(3} = \frac{391}{144}$
