Question

1) (-11)² ; 4) (-4)³ ; 7) (-10)²+ 97;
2) (-0,7)² ; 5) (-0,2)³ ; 8) (-0,9)² -1 ;
3) (-2/5)² 6) (-1/2)³ ; 9) (-2/3)³ -1 .

Answer 1

1. -11*-11=121

2. -0,7*-0,7=0,49

3. -2/5*-2/5=4/25 = 0,16

4. -4*-4*-4= -64

5.  -0,2*-0,2*-0,2=-0,008

6. -1/2*-1/2*-1/2=-1/8=-0,125

7. -10*-10 + 97 = 100+97=197

8. -0,9*-0,9 - 1 = 0,81-1=-0,19

9. -2/3*-2/3*-2/3 - 1 = -8/27 - 1 = -8/27 - 27/27 = -35/27
