expand 4wn(3in^4+5iner-4i)

expand

4 w n (3 i n^{4} + 5 in er - 4 i)

12 n^{5} i w + 20 e n^{2} i w r - 16 ni w

Solution steps

4 w n (3 i n^{4} + 5 in er - 4 i)

= 4 n w (3 n^{4} i + 5 e ni r - 4 i)

Distribute parentheses

= 4 w n \cdot 3 i n^{4} + 4 w n \cdot 5 in er + 4 w n (- 4 i)

Apply minus-plus rules

+ (- a) = - a

= 4 \cdot 3 n^{4} ni w + 4 \cdot 5 e nni w r - 4 \cdot 4 ni w

Simplify

4 \cdot 3 n^{4} ni w + 4 \cdot 5 e nni w r - 4 \cdot 4 ni w : 12 n^{5} i w + 20 e n^{2} i w r - 16 ni w

= 12 n^{5} i w + 20 e n^{2} i w r - 16 ni w

\frac{( 2 x - 3 ) ( x + 1 )}{( x - 1 ) ( x - 2 )}

(- vx + 2 x) (v + x \frac{d v}{d x})

(x + 2) d x + (y - 2) d y

\frac{x ^{2} + x + 1}{x ( x ^{2} + 1 )}

(- x)^{3}
