Question

if a,b,c 3 positive numbers not all equal then prove that by inequalities

Answer 1

★ ARITHMETIC AND GEOMETRIC PROGRESSION AT IT'S BEST ★

APPLYING AM-GM INEQUALITY on ( b + c ) , ( c + a ) , ( a + b ) for obtaining the first relationship in inequality and applying AM-GM INEQUALITY on 1/ b+c , 1/c+a , 1/a+b for obtaining the second relationship in inequality , then multiplying both the results to obtain the final inequality .
