expand (x^3y)/((x+3)^4)

expand

\frac{x ^{3} y}{( x + 3 ) ^{4}}

\frac{x ^{3} y}{x ^{4} + 12 x ^{3} + 54 x ^{2} + 108 x + 81}

Solution steps

\frac{x ^{3} y}{( x + 3 ) ^{4}}

(x + 3)^{4} = x^{4} + 12 x^{3} + 54 x^{2} + 108 x + 81

= \frac{x ^{3} y}{x ^{4} + 12 x ^{3} + 54 x ^{2} + 108 x + 81}

\frac{( 34 + 2 x ^{2} + 12 s )}{x ( x ^{2} - 2 s + 17 )}

(12 - 12 e^{- \frac{t}{x}})^{2}

A (- 2, 4, - 7) \cdot B (5, - 1, 3)

e^{x} (- \frac{1}{3} cos (3 x) + C)

(a + b - c) (d + e)
