Answer 1

$\sqrt{75}$ = $\sqrt{25*3}$  = 5*$\sqrt{3}$ 
$\sqrt{48}$ = $\sqrt{16*3}$  = 4*$\sqrt{3}$ 
5*$\sqrt{3}$  - 4*$\sqrt{3}$  = $\sqrt{3}$ 
$\sqrt{3}$ *$\sqrt{12}$ = $\sqrt{3*12}$ = $\sqrt{36}$ = 6
Ответ: 6

Answer 2

√75*√12-√48√12=√(75*12)-√(48*12)=√(25*3*3*4)-√(12*4*12)=√25√(3*3)√4-√(12*12)√4=
5*3*2-12*2=30-24=6
