s^² =
x1^²* p1+ x2^²* p2+ x3^²* p3- x__v^²

s^² = x1^²* p1+ x2^²* p2+ x3^²* p3- x__v^² $s^{2}$ = $x1^{2}\cdot p1+x2^{2}\cdot p2+x3^{2}\cdot p3-x_{v}^{2}$

s^² = p1* x1^²+ p2* x2^²+ p3* x3^²- x__v^² $s^{2}$ = $p1\cdot x1^{2}+p2\cdot x2^{2}+p3\cdot x3^{2}-x_{v}^{2}$

s = saknis(

p1* x1^²+ p2* x2^²+ p3* x3^²- x__v^²) $s$ = $\sqrt {p1\cdot x1^{2}+p2\cdot x2^{2}+p3\cdot x3^{2}-x_{v}^{2}}$
