Correction
24
1) -14 + 4 x 9 = -14 +36=22
25
2) 26 – (-6) x 7 = 26 +42=68
26
3) – 5 3 =- 5 x 5x 5 =-125
27
4)10 +3 3 = 10 +3 x 3x 3=10 +27 = 37
28
5) (-1) 4 =(-1) x (-1) x (-1) (- 1) =1
29
6)(-1-5)²=(-6)² =(-6) x (-6) = 36
30
7) (-81) : (-9) =81:9=9
31
8) (-2,7) : 0,5 = - 2,7 x 2=-5,4
32
9) 0,68 : 0,1 = 0,68 x 10 = 6,8
33
10) x 2 pour x = 10 10² = 10 x 10 = 100
