expand (x+4y)^{12}

Solution

expand

(x + 4 y)^{12}

Solution

x^{12} + 48 x^{11} y + 1056 x^{10} y^{2} + 14080 x^{9} y^{3} + 126720 x^{8} y^{4} + 811008 x^{7} y^{5} + 3784704 x^{6} y^{6} + 12976128 x^{5} y^{7} + 32440320 x^{4} y^{8} + 57671680 x^{3} y^{9} + 69206016 x^{2} y^{10} + 50331648 x y^{11} + 16777216 y^{12}

Solution steps

(x + 4 y)^{12}

Apply binomial theorem:

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

a = x, b = 4 y

= i = 0 \sum 12 (i 12) x^{(12 - i)} (4 y)^{i}
