Question

Cine ma poate ajuta cu (√27-4)(3√3-4)???

Answer 1

$( \sqrt{27} - 4)(3 \sqrt{3} - 4) = (3 \sqrt{3} - 4)(3 \sqrt{3} - 4) = ({3 \sqrt{3} - 4})^{2} = ({3 \sqrt{3} )}^{2} - 2 \times 3 \sqrt{3} \times 4 + {4}^{2} = 27 - 24 \sqrt{3} + 16 = 43 - 24 \sqrt{3}$

Answer 2

(√27 - 4)(3√3-4) = (3√3-4)(3√3-4) = $(3\sqrt{3}) ^{2}$ - 2*3√3*4 + $4^{2}$ = 9*3 - 24√3 + 16 = 27 - 24√3 + 16 = 43 - 24√3

Rezultat final: 43 - 24√3
