bonjour
calculer
5² =5×5=25
5⁻²=1/5×1/5=0.04
(-5)²= (-5)×(-5)=25
-5²=-5×5=-25
(-0.4)³=(-0.4)×(-0.4)×(0.4)=-0.064
0.4⁻³=1/0.4×1/0.4×1/0.4=15.625
(-0.4)⁻³=(1/-0.4)×(1/-0.4)×(1/-0.4)=-15.625
0³=0
3¹=3
(-3)¹=-3
-3¹=-3
(1/4)²=1/4 ×1/4=1/16
(-1/4)⁴=(-1/4)×(-1/4)×(-1/4)×(-1/4)=1/256
(1/4)⁻²=4×4=16
(-1/4)⁰=1
(3/5)³=3/5× 3/5× 3/5=27/125
(3/5)⁻³=5/3×5/3×5/3=125/27
(-3/5)³=(-3/5)×(-3/5)×(-3/5)=-27/125
-(3/5)⁰=-1
