(5√2-√18)*√2
(3-√2)на верху с копки 2

Answer 1

1)
$10sqrt{3}-sqrt{48}-sqrt{75}=10sqrt{3}-sqrt{3}*sqrt{16}-sqrt{3}*sqrt{25}=\=sqrt{3}(10-sqrt{16}-sqrt{25})=sqrt{3}(10-4-5)=sqrt{3}$

2)
$(5sqrt{2}-sqrt{18})sqrt{2}=5sqrt{2*2}-sqrt{18*2}=5sqrt{4}-sqrt{36}=5*2-6=4$

3)
$(3-sqrt{2})^2=3^2-2*3*sqrt{2}+(sqrt{2})^2=9-6sqrt{2}+2=11-6sqrt{2}$
