expand (x^{1/3}+y^{1/3})^{12}

expand

(x^{\frac{1}{3}} + y^{\frac{1}{3}})^{12}

x^{4} + 12 x^{\frac{11}{3}} y^{\frac{1}{3}} + 66 x^{\frac{10}{3}} y^{\frac{2}{3}} + 220 x^{3} y + 495 x^{\frac{8}{3}} y^{\frac{4}{3}} + 792 x^{\frac{7}{3}} y^{\frac{5}{3}} + 924 x^{2} y^{2} + 792 x^{\frac{5}{3}} y^{\frac{7}{3}} + 495 x^{\frac{4}{3}} y^{\frac{8}{3}} + 220 x y^{3} + 66 x^{\frac{2}{3}} y^{\frac{10}{3}} + 12 x^{\frac{1}{3}} y^{\frac{11}{3}} + y^{4}

Solution steps

(x^{\frac{1}{3}} + y^{\frac{1}{3}})^{12}

Apply binomial theorem:

(a + b)^{n} = i = 0 \sum n (i n) a^{(n - i)} b^{i}

a = x^{\frac{1}{3}}, b = y^{\frac{1}{3}}

= i = 0 \sum 12 (i 12) (x^{\frac{1}{3}})^{(12 - i)} (y^{\frac{1}{3}})^{i}
