expand (5x^6+2x^3)^4

expand

(5 x^{6} + 2 x^{3})^{4}

625 x^{24} + 1000 x^{21} + 600 x^{18} + 160 x^{15} + 16 x^{12}

Solution steps

(5 x^{6} + 2 x^{3})^{4}

Apply binomial theorem:

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

a = 5 x^{6}, b = 2 x^{3}

= i = 0 \sum 4 (i 4) (5 x^{6})^{(4 - i)} (2 x^{3})^{i}

Expand summation

= \frac{4 !}{0 ! ( 4 - 0 ) !} (5 x^{6})^{4} (2 x^{3})^{0} + \frac{4 !}{1 ! ( 4 - 1 ) !} (5 x^{6})^{3} (2 x^{3})^{1} + \frac{4 !}{2 ! ( 4 - 2 ) !} (5 x^{6})^{2} (2 x^{3})^{2} + \frac{4 !}{3 ! ( 4 - 3 ) !} (5 x^{6})^{1} (2 x^{3})^{3} + \frac{4 !}{4 ! ( 4 - 4 ) !} (5 x^{6})^{0} (2 x^{3})^{4}

Simplify

\frac{4 !}{0 ! ( 4 - 0 ) !} (5 x^{6})^{4} (2 x^{3})^{0} : 625 x^{24}

Simplify

\frac{4 !}{1 ! ( 4 - 1 ) !} (5 x^{6})^{3} (2 x^{3})^{1} : 1000 x^{21}

Simplify

\frac{4 !}{2 ! ( 4 - 2 ) !} (5 x^{6})^{2} (2 x^{3})^{2} : 600 x^{18}

Simplify

\frac{4 !}{3 ! ( 4 - 3 ) !} (5 x^{6})^{1} (2 x^{3})^{3} : 160 x^{15}

Simplify

\frac{4 !}{4 ! ( 4 - 4 ) !} (5 x^{6})^{0} (2 x^{3})^{4} : 16 x^{12}

= 625 x^{24} + 1000 x^{21} + 600 x^{18} + 160 x^{15} + 16 x^{12}

f (x) = x e^{x} csc (x)

\int 9 e^{\frac{x}{4}} d x

\int_{- \infty}^{0} x e^{- x} d x

y = 5 x, (5, 5)

\int 3 x^{2} e^{2 x^{3}} d x
