Final answer:
The expression is equal to 0 when x=0.
Step-by-step explanation:
To find the expression that is equivalent to 2x sqrt(44x)-2 sqrt(11x³) when x=0, we substitute x=0 into the given expression:
2(0)sqrt(44(0))-2sqrt(11(0)³)
This simplifies to:
0-0
Therefore, the expression is equal to 0 when x=0.
