A) (2x³+3y⁵)²
(2x³)² + 2.(2x³).(3y⁵) + (3y⁵)²
[tex]4x^{6} + 12x^{3}. y^{5} + 9y^{10}[/tex]
B) (x+1/3)²
[tex]x^{2} + 2.x.\frac{1}{3} + ({\frac{1}{3}})^2[/tex]
[tex]x^{2} + \frac{2x}{3} + \frac{1}{9}[/tex]
C) (x/2+x/5)²
[tex](\frac{x}{2})^2 + 2.\frac{x}{2}.\frac{x}{5} + (\frac{x}{5})^{2}\\[/tex]
[tex]\frac{x^{2} }{4} + \frac{2.x^{2}}{10} + \frac{x^{2} }{25}[/tex]
[tex]\frac{x^{2}}{4} + \frac{x^{2} }{5} + \frac{x^{2} }{25}[/tex]
[tex]\frac{25x^{2} + 20x^{2} + 4x^{2}}{100} = \frac{49x^{2} }{100}[/tex]
