expand (16)/((x^2+4)^2)

expand

\frac{16}{( x ^{2} + 4 ) ^{2}}

\frac{16}{x ^{4} + 8 x ^{2} + 16}

Solution steps

\frac{16}{( x ^{2} + 4 ) ^{2}}

(x^{2} + 4)^{2} = x^{4} + 8 x^{2} + 16

= \frac{16}{x ^{4} + 8 x ^{2} + 16}

1 \frac{1}{5} (1 - \frac{5}{6})

(4 x y + 2 y + x^{3}) d x + (2 y^{2} + 3 x^{2} y) d y

(9 x - 13 x^{3} + 12 - 15 x^{2}) l e f t (- 2 x^{3})

(3 - \frac{x}{2})^{8}

x^{\frac{3}{2}} (4 - 4 x)
