You asked:

Evaluate the expression: \(3 \cdot \sqrt{3} - -\sqrt{27}\)

MathBot Answer:

\[3 \cdot \sqrt{3} - -\sqrt{27} = 6 \sqrt{3} \approx 10.39230484541326376116467804903523\]

\[\begin{aligned}3 \cdot \sqrt{3} - -\sqrt{27}& = 3 \cdot \sqrt{3} - - \sqrt{27}\\& = 3 \cdot \sqrt{3} - - 3 \cdot \sqrt{3}\\& = 3 \cdot \sqrt{3} - -3 \cdot \sqrt{3}\\& = 3 \cdot \sqrt{3} + 3 \cdot \sqrt{3}\\& = 6 \cdot \sqrt{3}\end{aligned}\]
