Simplify:

1)(mn^2/3)(4/mn)

2)(x+4/x-4)(1/x+4)

3)(x^2-16/2x+8)(x+4/x^2+8x+16)

4)(n/4)(n/m)

5)(3a^3-27a/2a^2+13a-7)(9a^2/4a^2-1)

3)(x^2-16/2x+8)(x+4/x^2+8x+16)

[(x-4)(x+4) / 2(x+4 )][(x+4)/[(x+4)(x+4]]

[(x-4)/2)][1/(x+4)]

(x-4)/(2x+8)

**Damon**, Thursday, August 7, 2008 at 4:21pmI do not think m is supposed to be squared the way you typed it, only n

(m n n /3) (4 / m n)

4 n / 3
