Answer:
x=100
Explanation:
a=5√(2)
2a=2√(2x)
Multiply the first equation by 2 on both sides to get:
2a=2*5√(2)=10√(2)
Now, since we have 2a on the left sides of both equations, we can solve this.
10√(2)=√(2x)
We can rewrite √(2x) as √(2) * √(x) and divide by √(2) on both sides.
10=√(x)
Square on both sides to get:
100=x
So x=100. Hope I could help you!
