Bonjour
Explications étape par étape
A = 7 +2 X 5²
A = 7 +2 X 25
A = 7 +50 = 57
B = (9 -4 -1)⁵
B = (9 -5)⁵
B = 4⁵ = 1 024
C = (-2 X 4 -6)²
C = (-8 -6)²
C = -14²
C = + 196
bonjour
A = 7 + 2 *5 ²
A = 7 + 2 *25
A = 7 +50 = 57
B = 9 - ( 4 * - 1 ) ⁵
B = 9 - ( - 4 ) ⁵
B = 9 - ( - 1024)
B = 9 + 1204 = 1 033
C = ( - 2 x 4 - 6 )²
C = ( - 8 - 6 )²
C = ( - 14 )² = 196
