Ответ:

$\frac{1}{16} p^{2} +2py +16y^{2}$

Объяснение:

$(\frac{1}{4} p+4y)^{2} =$

$= (\frac{1}{4} p+4y)*(\frac{1}{4} p+4y) =$

$=\frac{1}{4} p*(\frac{1}{4} p+4y)+4y *(\frac{1}{4} p+4y) =$

$=(\frac{1}{4} p*\frac{1}{4}p+\frac{1}{4} p*4y)+(4y *\frac{1}{4} p +4y*4y) =$

$=(\frac{1}{16} p^{2} +py)+(py +16y^{2} ) =$

$=\frac{1}{16} p^{2} +py+py +16y^{2} =$

$=\frac{1}{16} p^{2} +2py +16y^{2}$
