Answer:


=10√(10)+10√(2)-10√(5)-10

Explanation:


(2√(5) -√(10))(5√(2)+√(10))


=2√(5)\cdot5√(2)+2√(5)√(10)-5√(2)√(10)-√(10)√(10)


=10√(10)+2√(50)-5√(20)-10


=10√(10)+2√(25 \cdot 2)-5√(4 \cdot5)-10


=10√(10)+2√(25)√(2)-5√(4)√(5)-10


=10√(10)+2\cdot5√(2)-5\cdot2√(5)-10


=10√(10)+10√(2)-10√(5)-10
