Answer 1

$a) \\ \\ (3x + 1)^2 \\ \\ (3x + 1)*(3x + 1) \\ \\ => 9x^2 + 6x + 1$

====
$b) \\ \\ (10x + y)^2 \\ \\ (10x + y)*(10x + y) \\ \\ => 100x^2 + 2xy + y^2$

====
$c) \\ \\ (xy + p^3)^2 \\ \\ (xy + p^3)*(xy + p^3) \\ \\ => p^6 + 2xyp^3 + x^2y^2$

====
$d) \\ \\ (ac + d^3)^2 \\ \\ (ac + d^3)*(ac + d^3) \\ \\ => d^6 + 2acd^3 + a^2c^2$

====
$e) \\ \\ (2m + n/2)^2 \\ \\ (2m + n/2)*(2m + n/2) \\ \\ => \dfrac{16m^2 + 8mn +n^2}{4}$

====
$f) \\ \\ (x/2 + y/2)^2 \\ \\ (x/2 + y/2)* (x/2 + y/2) \\ \\ => \dfrac{x^2 + 2xy + y^2}{4}$

====
$g) \\ \\ (4m^2 - 1)^2 \\ \\ (4m^2 - 1)*(4m^2 - 1) \\ \\=> 16m^4 - 8m2 + 1$

====
$h) \\ \\ (a^2c - 3x)^2 \\ \\ (a^2c - 3x)* (a^2c - 3x) \\ \\ => a^4c^2 + 6xca^2 + 9x^2$
