Sagot :
bonjour
A = 5 + 4 = 9
B = 7 ² = 49
C = 5 - 4 = 1
D = 3 ² = 9
E = 5 * 4 = 20
F = 10 ² = 100
A = ( 8 - 6 ) ² = 2 ² = 4
B = 8 - 3 * 4 = 8 - 12 = - 4
C = 5 * 4 = 20
D = 8 - ( 6 )² = 8 - 36 = - 28
A = 2 + 3 * 25 = 2 + 75 = 77
B = (- 16 - 15 ) : 4 = - 31 : 4 = - 7.75
Réponse :
Bonsoir,
73) A= 5 + 2²
A= 5 + 4
A= 9
B= (5 + 2)²
B= 7²
B= 49
C= 5 - 2²
C= 5 - 4
C= 1
D= (5 - 2)²
D= 3²
D= 9
E= 5 x 2²
E= 5 x 4
E= 20
F= (5 x 2)²
F= 10²
F= 100
75) A= 2 + 3 x 5²
A= 2 + 3 x 25
A= 2 + 75
A= 77
B= -2^4 + 3 x (-5) / 2²
B= -16 - 15 / 4
B= -31 / 4
