6√7 + 3√3 - 2√7
You asked:
Evaluate the expression: \(6 \cdot \sqrt{7} + 3 \cdot \sqrt{3} - 2 \cdot \sqrt{7}\)
MathBot Answer:
\[6 \cdot \sqrt{7} + 3 \cdot \sqrt{3} - 2 \cdot \sqrt{7} = 3 \sqrt{3} + 4 \sqrt{7} \approx 15.77915766696499424258880203907466\]
\[\begin{aligned}6 \cdot \sqrt{7} + 3 \cdot \sqrt{3} - 2 \cdot \sqrt{7}& = \left(3 \cdot \sqrt{3} + 6 \cdot \sqrt{7}\right) - 2 \cdot \sqrt{7}\\& = 3 \cdot \sqrt{3} + 4 \cdot \sqrt{7}\end{aligned}\]
