[tex]\boldsymbol{ \red{ 2\sqrt{30} }}[/tex]
Explicație pas cu pas:
[tex]\dfrac{(+5 \cdot 3\sqrt{2}) \cdot (+2 \cdot 5\sqrt{3})}{+15 \cdot\sqrt{5} } = \dfrac{\not15\sqrt{2} \cdot 10\sqrt{3}}{\not15 \cdot\sqrt{5} } = \\[/tex]
[tex]=\dfrac{^{\sqrt{5})}10\sqrt{2 \cdot 3} }{\sqrt{5}} = \dfrac{\not10\sqrt{6} \cdot \sqrt{5} }{\not5} = 2\sqrt{30} \\[/tex]
