b) [2⁹:2⁷+(3²×2-27)4¹-23⁰]=
c) [1+3 pe 4+(7 pe 2×1 pe 3) + 3 pe 24=

Ajutor repede!!!!!Dau coroană!!!​

Answer 1

a) {8+[9+(16+2)+1]+1+132}x9=
[8+(9+18+1)+1+132]x9=
(8+28+1+132)x9=
169x9=
1521

b)2^9:2^7=2^9-7=2^2
[2^2+(9x2-27)x4-1]=
4+(-9)x4-1=
4-9x4-1=
4-36-1=
-41

c)

Answer 2

Explicație pas cu pas:

a)

$= (8 + 9 + 16 + 2 + 1 + 1 + 132) \times 9 \\ = 169 \times 9 = 1521$

b)

$= {2}^{9 - 7} + (9 \times 2 - 27)4 - 1 = {2}^{2} + (18 - 27)4 - 1 \\ = 4 + ( - 9) \times 4 - 1 = 4 - 36 - 1 = 4 - 37 = - 33$

c)

$= 1 + \frac{3}{4} + \left( \frac{7}{2} \times \frac{1}{3} \right) + \frac{3}{24} \\ = 1 + \frac{3}{4} + \frac{7}{6} + \frac{3}{24}\\ = \frac{24 + 6 \times 3 + 7 \times 4 + 3}{24} \\ = \frac{24 + 18 + 28 + 3}{24} = \frac{73}{24} = 3 \frac{1}{24}$
