Answer:

Option D.

Explanation:

The given equation is


10b=5(√(c)+2)

We need to find an equation which is equivalent to the given equation.

Using distributive property, we get


10b=5(√(c))+5(2)


10b=5√(c)+10

Subtract both sides by 10.


10b-10=5√(c)

Divide both sides by 5.


(10b-10)/(5)=√(c)

Taking square on both sides.


\left((10b-10)/(5)\right)=(√(c))^2


((10b-10)^2)/(25)=c


c=((10b-10)^2)/(25)

This equation is equivalent to the given equation.

Therefore, the correct option is D.
