Я полагаю, надо приравнять к нулю первую производную Вашей функции.
Из решения уравнения f'(x,y)=0 Вы получите экстремумы.
Из найденных экстремумов в заданном аргумент-промежутке выберите решения с положительной второй производной , чтоб из экстремов отбраковать т-ко нужные минимумы.
Если математики не ответят, то я предчувствую, что Маткад справится с такой задачей. Но нужно ли Вам Маткад-решение?

Гордиенко Андрей Владимирович Вы поняли объяснение, ссылку на которое я Вам сообщил?
Да. Объяснение я поняла. Мне не пришло в голову использовать здесь неравенство Коши. Все другие способы получаются очень громоздкими.
Так что еще раз благодарю за ссылку!

Здравствуйте, kovalenina!
Эта задача рассмотрена здесь. Я думаю, что её решение выходит за рамки стандартной школьной программы по математике...
