Rationalize the denominator in the expression

Question

Rationalize the denominator in the expression

 

          -√2d

  t =     ----

            √a

 

Thank you in advance

Answer 1

 t = - √(2d) /√a =

 

    =   -^√(2d)  . √a =

            √a       √a 

 

     =  - √(2da)

             a

Answer 2

I assume the numerator is √(2d)
t = -√(2d)/√a

Multiply numerator and denominator by √a and get

t=-√(2ad)/a, in your given writing

      √(2ad)

t=- ---------

          a
