Question: what are the best values of $m$ and $n$

help me here:

suppose we have:


how can we find the best values of m and n such that h(x) > 0

one can show that for m = n = 1

h(x) > 0.

one may solve this by first finding the derivative of h(x)


and then solving

solve(diff(h(x),x),[m,n] )> 0

we may assume x > 0
