130=(60/sqrt(5x))

 

divide both sides by 60,

130/60 = 1/√(5x)

 

take reciprocal of both sides,

60/130 = √(5x)

 

reduce the factor by dividing top and bottom by 10,

6/13 = √(5x)

 

square both sides,

(6/13)2 = 5x

 

take ⅕ of each side,

⅕ • (6/13)2 = x  

 

I leave it to you to use a calculator to evaluate the arithmetic.
