QM$\geq$AM$\geq $GM$\geq $HM
$\sqrt{\frac{x_{1}^{2}+x_{2}^{2}+\cdot \cdot \cdot +x_{n}^{2}}{n}} \geq \frac{x_{1}+x_{2}+\cdot \cdot \cdot +x_{n}}{n}\geq \sqrt[n]{x_{1}x_{2}\cdot \cdot \cdot x_{n}}\geq \frac{n}{\frac{1}{x_{1}}+\frac{1}{x_{2}}+\cdot \cdot \cdot \frac{1}{x_{n}}}$
I think it is a good and useful relation to discuss

Re: inequality of means (bomc)
হায় হায় আমার ৫০ নাম্বার পোস্টে ভুল ঠিক করতে হচ্চে।কারন উপরের পোস্ট টা এডিট করা যাবে না।
সবচেয়ে L.H.S টা হবে
$ \sqrt{\frac{x_{1}^{2}+x_{2}^{2}+\cdot \cdot \cdot +x_{n}^{2}}{n}}$
ওহ না, এডিট করে ফেলছি।কিন্তু এখন এই পোস্ট টা ডিলিট করা যাচ্ছে নাহ।

অন্তত একটা রিপ্লাই না হলে মনে হয় remove করা যায় না। এবার চেষ্টা করে দেখতে পার।
