A = -4 (-2)² - 2 x 3 = -16 - 6 = -22

1.2

y² + 8y + 16 - y² - y + 1

7y + 17

1.3

1/6 - 4/3 /  -1/2

1/6 - 8/6 / -1/2

-7/6 /-1/2 = 7/3

1.4

2**5 x 2**-2 = 8

(-5**-2)**-2 = 1/625

Bonjour

y= -2

A)

- 4*(-2)²  -2*-2

= - 16 +4 =  -12

y= 3

-4(3)² -2*3

= -4 *27 -6

= -108 -6 = -114

B)

y² +8y +16 -( y² -2y + 1)

=  y² +8y +16 - y² +2y - 1

= 10y +15

C)

(1/6 -8/6)  / ( -1/2)

= -7/6 * -2/1

14/6 = 7/3

D)

2*2*2*2*2 *2/100

32 *2/100

= 64/100 = 0,64

E)

-5
