Question

Cum se demonstreaza Inegalitatea lui Minkowski?

Answer 1

          
$\sqrt{\sum_{i=1} ^{n}(a_i + b_i)^{2}} \leq \sqrt{\sum_{i=1} ^{n}a_i ^{2}}+ \sqrt{\sum_{i=1} ^{n}(b_i + b_i)^{2}} \\ unde \, \, a_i,\, \, b_i \, \, apartin \, \, lui \, \, R, \, \, oricare \, \, i \, \, de \, la\, 1\, la\, n.$
