simplify:
2sqrt50  sqrt8
I am confused because of the 2 before the sqrt50

2 sqrt 50 = 2 sqrt (5*5*2) = 10 sqrt 2
sqrt 8  sqrt (2*2*2) = 2 sqrt 2
10 sqrt 2  2 sqrt 2 = 
is 8sqrt2 correct?

The 2 before the sqrt50 just means 2 times sqrt50
Since
sqrt50=5sqrt2
and
sqrt8=2sqrt2
2*5sqrt22sqrt2
=10sqrt22sqrt2
=8sqrt2 
Yes, both right :)
