$\sqrt{3}$ - $\sqrt{15}$ + $\sqrt{1}$ $\sqrt{5}$
You asked:
Evaluate the expression: \(\sqrt{3} - \sqrt{15} + \sqrt{1} \cdot \sqrt{5}\)
MathBot Answer:
\[\sqrt{3} - \sqrt{15} + \sqrt{1} \cdot \sqrt{5} = - \sqrt{15} + \sqrt{3} + \sqrt{5} \approx 0.09513543886125010475735461045475\]
\[\begin{aligned}\sqrt{3} - \sqrt{15} + \sqrt{1} \cdot \sqrt{5}& = \sqrt{3} - \sqrt{15} + 1 \cdot \sqrt{5}\\& = \sqrt{3} - \sqrt{15} + \sqrt{5}\\& = \left(\sqrt{3} - \sqrt{15}\right) + \sqrt{5}\\& = \sqrt{3} + \sqrt{5} - \sqrt{15}\end{aligned}\]
