For the following equations, determine its order, degree (if exists)
$sqrt(("d"y)/("d"x)) - 4 ("d"y)/("d"x) - 7x$ = 0
$sqrt(("d"y)/("d"x)) = 4 ("d"y)/("d"x) + 7x$
On squaring both sides,
$("d"y)/("d"x) = 16(("d"y)/("d"x))^2 + 49x^2 + 56x ("d"y)/("d"x)$
clearly, it is a differential equation of order = 1 and degree = 2.
