$15 \sqrt{2} - 10 \sqrt{42}$ $15sqrt2-10sqrt42$

$5 \sqrt{6} (\sqrt{3} - 2 \sqrt{7})$ $5sqrt6(sqrt3-2sqrt7)$

$\Rightarrow 5 \sqrt{6} \cdot \sqrt{3} - 10 \sqrt{6} \cdot \sqrt{7}$ $=>5sqrt6*sqrt3-10sqrt6*sqrt7$

$\Rightarrow 5 \sqrt{9 \cdot 2} - 10 \sqrt{42}$ $=>5sqrt(9*2)-10sqrt42$

$\Rightarrow 15 \sqrt{2} - 10 \sqrt{42}$ $=>15sqrt2-10sqrt42$
