aidez moi svp. je dois faire tout les calculs detailler mais jai pas tout reussi

Bonsoir , 
A = 29 × 10⁻² + 133,1 × 10⁻¹ - 0,036 × 10²
A = 162,064 × 10⁻²⁺⁻¹⁺²
A = 162,064 × 10⁻¹
A = 1,62064 × 10¹
B = -3a² - 4a + 6 
B = -3(-5)² - 4(-5) + 6
B = -75 + 20 + 6
B = -49
C = -4 + 2 × ( -3 × -2 - 9 )
C = -4 + 2 × -3
C = -4 + -5
C = -9
D = 15/16 × 4/9 + 1/12
D = 60/144 + 1/12
D = 5/12 + 1/12
D = 6/12
D = 1/6
E = (8 + 2/3) ÷ (8-2/3)
E = (24/3 + 2/3) × (24/3-2/3)
E = 26/3 × 22/3
E = 572/9
F = 35 × 10²² × 2 × (10⁻²)⁶ / 42 × 10¹⁰
F = 70 × 10²² × 10⁻¹² / 42 × 10¹⁰
F = 70/42 × 10²²⁻¹²⁻¹⁰
F = 1,66 × 10⁰
F = 1,66
