1. The problem statement, all variables and given/known data

Show that ||x||1 < or = n||x||infinity and ||x||2 < or = sqrt(n)*||x||infinity for x exists in the set of all real numbers.

2. Relevant equations

||x||2 is defined here: http://mathworld.wolfram.com/L2-Norm.html

||x||1 is defined here: http://mathworld.wolfram.com/L1-Norm.html

||x||infinity is defined here: http://mathworld.wolfram.com/L1-Norm.html

Sorry about posting links, but I have no idea how to get all the symbols (like the summation symbol) to show up on the forums!

Thanks in advance for your help!!
