To determine unique constants \(x,y\), interpret the equality as an identity for all independent positive bases \(m,n\). For fixed unspecified \(m,n\), one equation generally does not determine both unknowns.

If \(\frac{m^x}{n^y} \times \frac{n^{4-3x}}{(m^{y+1})^2} = \frac{n^7}{m^{10}}\), find the value(s) of \(x\) and \(y\).
