A)
{[(10-3) - 15] : 8 + 4} • 8 - [ (5 • 8) • 10 - 100]=
[(7 -15) : 8 + 4] • 8 - (40 • 10 -100) =
[(-8) : 8 + 4] • 8 - ( 400-100) =
[(-1) + 4] • 8 - 300 =
3 • 8 -300 =
24 - 300 =
- 276

B)
(-5)^87 : [(-5)^3 • (-5)^14]^5 + 10 • [(-20)^2 - 15^2] =
(-5)^87 : [(-5)^17]^5 + 10 • (400 - 225) =
(-5)^87 : (-5)^85 + 10 • 175 =
(-5)^2 + 1750 =
25 + 1750 =
1775

a) {[(10-3)-15]:8+4}•8-[(5-8)•10-10^2]=

[(7-15):8+4]•8-(-3•10-10^2)=

(-8:8+4)•8-(-30-100)=

(-1+4)•8-(-130)=

3•8+130=

24+130=154

b) (-5)^87 : ((-5)^17)^5+10•(400-225)=

(-5)^87 : (-5)^85+10•175=

(-5)^2+1750=

25+1750=1775
