Question

Решите Е пожалуйста!!!!!

Answer 1

(√0,75+√9*1:27-√6,75)*√3=(√0,75+√1:3-√6,75)*√3=(-√6+√1:3)*√3=-√18+1=3√2+1

Answer 2

(√0,75+3*√(1/27)-√6,75)*√3=(√(0,25*3)+3*√((1/3)²*(1/3))-√(0,25*9*3))*√3=
=(√(0,5²*3)+3*(1/3)*√(1/3)-√(0,5²*3²*3))*√3=(0,5*√3)+√(1/3)-(0,5*3)*√3)*√3=
=(0,5*√3+1/√3-1,5√3)*√3=(1/√3-√3)*√3=(√3/3-√3)*√3=3/3-3=1-3=-2.
