Derivations of dimensions problem

    1. The problem statement, all variables and given/known data
    Dimensions: These derivations are not correct ( as stated by the book)

    I'm just reading my textbook at the moment and I saw this example ( So I don't have work for it myself by the book shows all the steps).

    ***√[L]/[L/T^2] =√[T^2]


    2. Relevant equations



    3. The attempt at a solution

    I just want this to be explained as the book does not explain it, it just shows steps.

    How does***√[L]/[L/T^2] equal √[T^2]?

    Re: Dimensions

    Do you mean [tex]
    \sqrt {\frac{{[L]}}{{\frac{{[L]}}{{[T]^2 }}}}} [/tex] ??

    Re: Dimensions

    [tex]
    \frac{L}{L/T^2}
    [/tex]

    Multiply both sides by T^2, simply, and you'll get the answer.
