33−−27=63≈10.392304845413263761164678049035233 \sqrt{3} - -\sqrt{27} = 6 \sqrt{3} \approx 10.3923048454132637611646780490352333−−27=63≈10.39230484541326376116467804903523
33−−27=3⋅3−−27=3⋅3−−3⋅3=3⋅3−−3⋅3=3⋅3+3⋅3=6⋅3\begin{aligned}3 \sqrt{3} - -\sqrt{27}&=3 \cdot \sqrt{3} - - \sqrt{27}\\&=3 \cdot \sqrt{3} - - 3 \cdot \sqrt{3}\\&=3 \cdot \sqrt{3} - -3 \cdot \sqrt{3}\\&=3 \cdot \sqrt{3} + 3 \cdot \sqrt{3}\\&=6 \cdot \sqrt{3}\end{aligned}33−−27=3⋅3−−27=3⋅3−−3⋅3=3⋅3−−3⋅3=3⋅3+3⋅3=6⋅3
