a)(√3)⁵ :( -√3³)-3×√0,(3)×(1/√3)⁻³=
=9√3 :(-3√3)-3×√(3/9)×√3³=
=-3-√3×3√3=
=-3-9=-12


b){√6561× [-3,4(1)]/[-27,9]-(4/3)⁻²×0,(4)}×(-6/√7)²×1/10=
3,4(1)=(341-34)/90=307/90
27,9=279/10
0,(4)=4/9
={81× (-307/90)/(279/10)-(3/4)²×4/9}×36/7×1/10=
={81× (-307/9)/279 -9/16×4/9}×36/7×1/10=
=(-307/31-1/4)×36/7×1/10=
=(-1228-31)/124 ×36/70=
=(-1197)/124 ×36/70=
=(-171)/31 ×9/10=
=-1539/310
