Answer 1

6. -5-(-2)= -5+2 = -3
7. -8-10=-18 
8. -4+(-5)=-4-5=-9
9. -5-(-2+3-8+6)=-5+2-3+8-6 = -3+5-6=-4
10. (-5)*(-14)=-5 . -14 = 70
11. (-10)*(-2)=-10. -2 = 20
12. (-10)-(-2)=-10+2 = -8
13 (-10)*(2)=-10.2 = -20 
14. (-10)+(2)=-8
15. (-10)^2=-10. -10 =100
16.(-10)^3=-10. -10. -10 = -1000
17. √ -100=√100√-1 = 10.i=10i
18.√ 100=√10²=10
19. 3/4+1/4=3+1/4=1
20. 3/4 + 1/8= 3.8+4/4.8 = 28/32 = 14/16 = 7/8
21. 3/4-1/4= 3-1/4 = 2/4 = 1/2
22. 3/4+1/8-3/5= 7/8-3/5 = 7.5-8.3/8.5 = 45-24/40 = 21/40 
23. 2+1/8-3/5= 2.8+1/8 - 3/5 = 17/8-3/5 = 17.5-8.3/8.5 =61/40
24.(3/5)^2= 3²/5² = 9/25
25.(- 3/5)^2= -3²/5² = 9/25
26. (9/25)^-2 = 9⁻²/25⁻² = 1/81 / 1/625 = 625/81 
27. (-9/25)^-2=-9⁻²/25⁻² = -1/81/-1/625 = -625/-81=625/81
28. (9/25)^1/2=9¹⁽²/25¹⁽²= 3/5  
29. (9/25)^-1/2=9⁻¹⁽² / 25⁻¹⁽²= -3/-5 = 3/5
