Sagot :
Bonjour,
1. A=-2 x (2-5) - 10
= -2* -3 -10
= 6 -10
= -4
3. C=-2 (2-5) - 10 (-3)
= -2* -3 +30
= 6 +30
= 36
5. E= -0,2 x (2-12) + 10
= -0,2 * -10 +10
= 2+10
= 12
6. F=1-2+3-4+5-6 + 7-8
= 1+3 +5 +7 -(2+4+6+8)
= 16 - 20
= -4
2. B = -2 x 1(2-5) 3-10]
il manque le crochet
4. D=3,14x2,5x(-50) x 4x(-2)
= 3,14 * (- 125) * (- 8)
= 3 140
1. A=-2 x (2-5) - 10
=-16
3. C=-2 (2-5) - 10 (-3)
=36
5. E= -0,2 x (2-12) = 10
=2
6. F=1-2+3-4+5-6 + 7-8
=-4
2. B = -2 x 1(2-5) 3-10]
=8
4. D=3,14x2,5x(-50) x 4x(-2)
=12
bonne journée
