Find the maximum and minimum values of the expression $\displaystyle P=\frac{ab}{c} +\frac{bc}{a} +\frac{ca}{b}$. Where $\displaystyle a,b,c$ are positive real numbers satisfying the condition $\displaystyle min\left \{ a,b,c \right \}\geq \frac{1}{4}max\left \{ a,b,c \right \}$

Hey leezangqe.
What class is this in? Is this in multivariable calculus or in an optimization course? Have you learned Lagrange Multipliers?

Re: Inequalities hard
can you explain more clearly?
