Question

(5x+3y²)²
(m+3a)² 
(x+a²)²
(a³+5b)²
(y+2/3)²

Answer 1

(5x + 3$y^{2}$)$^{2}$
25$x^{2}$ + 2.5x.3$y^{2}$ + 9$y^{4}$
25$x^{2}$ + 30x$y^{2}$ + 9$y^{4}$

(m + 3a)$^{2}$
$m^{2}$ + 2.m.3a + 9$a^{2}$
$m^{2} + 6m.a + 9 a^{2}$

(x + $a^{2}$)$^{2}$
$x^{2} + 2x a^{2} + a^{4}$

($a^{3} + 5b$)$^{2}$
$a^{6} + 2. a^{3}.5b + 25 b^{2}$
$a^{6} + 10 a^{3}b + 25 b^{2}$

($y^{2} + \frac{2}{3}$)$^{2}$
$y^{2} + 2.y. \frac{2}{3} + \frac{4}{9}$
$y^{2} + \frac{4y}{3} + \frac{4}{9}$
