1.  3m/n * n^2/6

3mn^2/6n

mn/2

 

2.  (x-5)^3/2 * 1/(x-5)

(x-5)^3/2(x-5)

(x-5)^2/2

 

3.  x^2-9/x+2 * x^-4/x-3

(x+3)(x-3)/(x+2) * (x+2)(x-2)/(x-3)

(x+3)(x-3)(x+2)(x-2)/(x+2)(x-3)

(x+3)(x+2)

x^2 + 5x + 6

 

4.  x^2+5x+4/(x-9) * x+1/x^2-9

(x+4)(x+1)/(x-9) * (x+1)/(x+3)(x-3)

(x+4)(x+1)(x+1)/(x-9)(x+3)(x-3)
