-
74 × 7-4
74 × 7-4 = 74-4 = 70 = 1
-
143 + 147
143 + 147
C'est une addition, il n'y a rien a faire. -
(-3)4 × (-3)-8
(-3)4 × (-3)-8 = (-3)4-8 = (-3)-4
-
[(-5)2]-6
[(-5)2]-6 = (-5)2× (-6) = (-5)-12
-
(3 × 4)6
(3 × 4)6 = 126
-
(-8x)4
(-8x)4 = (-8)4x4 = 4096x4
-
34 × 1/32
34 × 1/32 = 34/32 = 34-2 = 32 = 9
-
105 × 106
105 × 106 = 105 + 6 = 1011
