6) (b^-4)^-1 × b^-4/(b^3)^-3 × b^8 = (b-4)^-1 × b^-4/ b^-9 × b^8 = (b-4)^-1 × b^-4/b^-1 = (b-4)^-1/b^3 = 1/b^3 × (b-4) = 1/b^4 - 4b^3

7) 0,7

8) 17

9) а) 1/4х^2 = 3х

х^2 = 12х

х^2 - 12х = 0

х(х-12) = 0

х=0

х-12=0

х1=0

х2=12

б) 7х^2 - 4х - 3= 0

7х^2 + 3х-7х-3 = 0

х(7х+3)-(7х+3)=0

(7х+3)(х-1)=0

7х+3=0

х-1=0

х1=-3/7

х2=1
