C={5532}

Answer 2

Explicație pas cu pas:

ex:5

x= 2,7= 27/ 10

y= 1 întreg 1/2= (1•2+1)/2 = 3/2

z= 1/x •(27/10 - 1/y •( 3/ 2)= 1• răsturnata (10/27) - 1• răsturnata (2/ 3)

z= 10/27 - 18/27

z= - 8/27

z•(x-y²)=

= -8/27•[27/10 - (3/2)²] = -8/27 • (27/10 - 6/4)

= - 8/27 • (54/20 - 30/20)

= - 8/27 • 24/20

= - 8/27 • 6/5

= -8/9 • 2/5

= - 16/45

ex: 6

n= 4/3 - 4/3 • [4/3 - (3/9)²] ÷ (4•9+8)/9

n= 4/3 - 4/3 • (4/3 - 9/81) ÷ 44/9

n= 4/3 - 4/3 • (108/81 - 9/81)• 9/44

n= 4/3 - 4/3 • 99/ 81 • 9/44

n= 4/3 - 4/3 • 11/9 • 9/44

n= 4/3 - 4/3 • 1/4

n= 4/3 - 1/3

n= 3/3

n= 1

ex: 9

a = -2 +4

a = 2

b = -3 -3 +2 • (-4)

b = -3 -3 -8

b = -6 -8

b = -14

(a-3•b)/(3•a+b) =

= [2-3•(-14)]/[3•2+(-14)]

= (2+38)/(6-12)

= 40/8

= 5/1

= 5
