# Math Help - transposing with sqrt and sqr

1. ## 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
Rob

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
