Answer 2

Answer:

$(3 - \sqrt{3} ) {}^{2} \\ apply \: (x - y) {}^{2} = {x}^{2} + {y}^{2} - 2xy \\ = (3) {}^{2} + ( \sqrt{3} ) {}^{2} - 2 \times 3 \times \sqrt{3} \\ = 9 + 3 - 6 \sqrt{3} \\ = 12 - 6 \sqrt{3} \\ = 12 - 6 \times 1.732 \\ = 12 -10.39 2 \\ = 1.607 \: \: ans \\ hint : ( \sqrt{n} ) {}^{2} = n$
