What is the square root of 2 times the square root of 4? In surd form

2 root 2

Step-by-step explanation:

Square root of 4 is 2

So you are doing root 2 times 2

Whicg is 2 root 2

Step-by-step explanation:

Hello : 
L1: x=−2t, y=1+2t, z=3t(1)
l2: x=−9+5s, y=5s, z=2+4s(2)
by(1) and(2) :
-2t =-9+5s(*)
1+2t = 5s (**)
3t = 2+4s (***)
by (*) : 5s = 9 - 2t
by(**) : 5s = 1+2t
1+2t = 9 - 2t
4t = 8
t = 2
sunsct in (***) : 3(2) = 2+ 4s 
4s =4
s= 1
subsct  s  and t in : L1 or L2
in : L2s=1
 x = -9+5 = -4
y = 5
z=2+4 = 6
same calcul in : L1    ... t = 2
x = -2(2) = -4
y = 1+2(2) = 5
z = 3(2) =6
conclusion : 
find the point of intersection of the two lines is : (-4 , 5 , 6)
