bonjour
A = 1.7 x 10 ² - 5 ² x 2
= 170 - 50 = 120
B = 10 x ( - 2 ) ⁴ + ( 3 x 2 )²
= 10 x 16 + 6 ²
= 160 + 36 = 196
C = ( 8 - 9 ) ¹¹ x ( - 6 ) - 3 ²
= - 1 x - 6 - 9
= 6 - 9 = - 3
A = ( - 5 ) ³ + 2 x 10
= - 125 + 20 = - 105
B = ( 2 + 10 )² - 3 x 20
= 12 ² - 60
= 144 - 60 = 84
C = ( 13 - 11 ) ⁵ : 16 + 5
= 32 : 16 + 5
= 2 + 5 = 7
D = 4 x 7 - 75 x 5 ⁰
= 28 - 75 x 1
= 28 - 75 = - 47
E = 6 x 4 - 10 / 27 + 5
= 14 / 32
= 7 /16
F = 2 + 3 x 25 - 8
= 2 + 75 - 8
= 69
