It sounds like you have (5/x2) * x13

By the commutative property of multiplication, I can rewrite this as (5x13)/x2
(Division is the same as multiplying by the reciprocal, so 5/x2 is the same as 5 * 1/x2)

I can then rewrite as 5 * x13/x2 . I can then reduce the fraction to 5x11 (5 * x13 - 2). 


I can also look at this with negative exponents: 5/x2 is the same as 5x-2 . Therefore, (5/x2)x13 = 5x-2x13 = 5x13 - 2 = 5x11
