Question

If a=5 square root of 2 and 2a=square root of 2x

Answer 1

`\huge\boxed{\sf x = 100}`

Explanation:

Given equation:

2a = √(2x)

Put a = 5√2

2(5√2) = √(2x)

We can also write √(2x) as √2√x

10√2 = √2√x

• Divide both sides by √2

So,

10 = √x

• Now, take square on both sides

(10)² = √(x)²

100 = x

OR

x = 100
