'''Solução:'''
Pelo teorema binomial:
<math>(x+2y)^3 = \binom{3}{0} x^3(2y)^0+\binom{3}{1} x^2(2y)^1+\binom{3}{2} x^1(2y)^2+\binom{3}{3} x^0(2y)^3 = x^3+6x^2y+12xy^2+8y^3</math>
Pelo teorema binomial:
<math>(x+2y)^3 = \binom{3}{0} x^3(2y)^0+\binom{3}{1} x^2(2y)^1+\binom{3}{2} x^1(2y)^2+\binom{3}{3} x^0(2y)^3 = x^3+6x^2y+12xy^2+8y^3</math>
