Sagot :
bonjour
A= (1/3)² = 1 /9
B= 5²/(-5)² = 25 /25 = 1
C= 1-3²/(1-3)² = - 8 / 4 = - 2
D= (-5)²/(-3)^3 = 25 / - 27
E= 1+2/(1+2)² = 3 / 9 = 1 /3
F= (-1)²/2^3 = 1 / 8
G= 1- (1/3)² = 1 - 1/9 = 8 /9
H= (1-1/3)² = ( 2 /3)² = 4 /9
Bonsoir,
A= (1/3)² = 1/9
B= 5²/(-5)² = 25/25 = 1
C= 1-3²/(1-3)² = -8 / -2² = -8/ 4 =-2
D= (-5)²/(-3)³ = 25/ -27
E= 1+2/(1+2)² = 3/ 9 = 1/3
F= (-1)²/2³ = 1/ 8
G= 1- (1/3)² = 1-1/9 = 9/9 - 1/9 = 8/9
H= (1-1/3)² =
1-1/3 = 3/3 -1/3 = 2/3
(2/3²) = 4/9
Merci d'avance
