m^6 +n^6 +375m^2 n^2 =1953125  ⇒m^6 +n^6 +3m^2 n^2 (125)=(125)^3   Compare it with:     (m^2 )^3 +(n^2 )^3 +3m^2 n^2 (m^2 +n^2 )                                                =(m^2 +n^2 )^3   ⇒m^2 +n^2 =125       m=(√(125−n^2 ))  Only for n=2,11,5,10   m∈Z^+   Hence  The solutions are  (m,n)=(2,11),(11,2),(5,10),(10,5)
