Explicație pas cu pas:

Salutare!

(J)

$\bf \sqrt{24}:\sqrt{2}-12\sqrt{60} :2\sqrt{5} +4\cdot2\sqrt{3} =$

$\bf \sqrt{24:2}-24\sqrt{15}:2\sqrt{5} +8\sqrt{3} =$

$\bf \sqrt{12}-12\sqrt{15:5} +8\sqrt{3} =$

$\bf 2\sqrt{3}-12\sqrt{3} +8\sqrt{3} =$

$\boxed{\bf -2\sqrt{3} }$

(K)

$\bf \sqrt{90}:\sqrt{10} \cdot \sqrt{11} =$

$\bf \sqrt{90:10} \cdot \sqrt{11} =$

$\bf \sqrt{9 \cdot 11} =$

$\boxed{\bf 3\sqrt{11}}$

(L)

$\bf \sqrt{2}(3\sqrt{5} -\sqrt{2})-\sqrt{5}(2\sqrt{2} -4\sqrt{5})=$

$\bf 3\sqrt{5\cdot2} -\sqrt{2\cdot2}-2\sqrt{2\cdot5} +4\sqrt{5\cdot5}=$

$\bf 3\sqrt{10} -2-2\sqrt{10} +4\cdot 5=$

$\bf \sqrt{10} -2+20=$

$\boxed{\bf \sqrt{10} +18}$
