Explicație pas cu pas:
a)
[tex] = (8 + 9 + 16 + 2 + 1 + 1 + 132) \times 9 \\ = 169 \times 9 = 1521[/tex]
b)
[tex]= {2}^{9 - 7} + (9 \times 2 - 27)4 - 1 = {2}^{2} + (18 - 27)4 - 1 \\ = 4 + ( - 9) \times 4 - 1 = 4 - 36 - 1 = 4 - 37 = - 33[/tex]
c)
[tex]= 1 + \frac{3}{4} + \left( \frac{7}{2} \times \frac{1}{3} \right) + \frac{3}{24} \\ = 1 + \frac{3}{4} + \frac{7}{6} + \frac{3}{24}\\ = \frac{24 + 6 \times 3 + 7 \times 4 + 3}{24} \\ = \frac{24 + 18 + 28 + 3}{24} = \frac{73}{24} = 3 \frac{1}{24}[/tex]
