a)(7+3*4)-(5+5*4)=
(7+12) -(5+20) =19-25=-6
b)-3*[2-(-6)²:(-9)]-2*[6-(-8)]=
-3(2-36:(-9)) - 2×14=
- 3(2+4)-28=-18-28=-46
c)[(-5)²*(-1-4)⁴*(+3-8)³]⁵:(-5)⁴³=
[25×(-5)^4×(-5)^3]^ 5:(-5)^43=
[ 25×625×(-125)]^5:(-5)^43=
[ 5^2×5^4×(-5)^3]^5:(-5)^43=
[(-5)^9]^5:(-5)^43=(-5)^45:(-5)^43=5^2=25
d) (-25:(-5)+27:(-9)]*3=[5+(-3)]×3=2×3=6
e) [(-3)²⁹: 3²⁸+2*(-5)]:13+(-11)⁰=
[(-3)^1-10]:13+1=(-3-10):13+1=-1+1=0
f) [|-3²+(-3)³|-(-3) +(-2)* (4-6)]: (-3) =
[|9-27|+3+(-2)×2]:(-3)=
(18+3-4):(-3)=17:(-3)=-17/3
