[tex]( \sqrt{27} - 4)(3 \sqrt{3} - 4) = (3 \sqrt{3} - 4)(3 \sqrt{3} - 4) = ({3 \sqrt{3} - 4})^{2} = ({3 \sqrt{3} )}^{2} - 2 \times 3 \sqrt{3} \times 4 + {4}^{2} = 27 - 24 \sqrt{3} + 16 = 43 - 24 \sqrt{3} [/tex]
(√27 - 4)(3√3-4) = (3√3-4)(3√3-4) = [tex](3\sqrt{3}) ^{2}[/tex] - 2*3√3*4 + [tex]4^{2}[/tex] = 9*3 - 24√3 + 16 = 27 - 24√3 + 16 = 43 - 24√3
Rezultat final: 43 - 24√3
