    transposing with sqrt and sqr

    Goodday , may someone please help with this . I would like to isolate the h on the other side of the = . Exchange it with the q.
    q=d^2*(sqrt(2*g*h))*pi/4
    Thanks

    Let k=sqrt(2gh)
    q=d^2kpi/4
    move the 4 so 4q=d&2kpi
    move pi so 4q/pi=d^2k
    move d^2 so 4q/pi.d^2=k
    square both sides so (4q/pi.d^2)^2= 2gh
    move 2g so 1/2g(4q/pi.d^2)^2=h
    Thanks from robhare
