expand (2x^2+a/(x^3))^{10}

expand

(2 x^{2} + \frac{a}{x ^{3}})^{10}

1024 x^{20} + 5120 a x^{15} + 11520 a^{2} x^{10} + 15360 a^{3} x^{5} + 13440 a^{4} + \frac{8064 a ^{5}}{x ^{5}} + \frac{3360 a ^{6}}{x ^{10}} + \frac{960 a ^{7}}{x ^{15}} + \frac{180 a ^{8}}{x ^{20}} + \frac{20 a ^{9}}{x ^{25}} + \frac{a ^{10}}{x ^{30}}

Solution steps

(2 x^{2} + \frac{a}{x ^{3}})^{10}

Apply binomial theorem:

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

a = 2 x^{2}, b = \frac{a}{x ^{3}}

= i = 0 \sum 10 (i 10) (2 x^{2})^{(10 - i)} (\frac{a}{x ^{3}})^{i}
