x/x-8 i need to know if it is undefined
---
It's undefined when x = 8
======================================
[b^3c^7/a^3d^4] * [a^2d^3/abc^4]
this needs to be reduced in simplest form
---
= (a^2/a^3)(b^3/b)(c^7/c^4)(*d^3/d^4)
Cancel factors that are common to a numerator and a denominator
= (1/a)(b^2/1)(c^3/1)(1/d)
---
= (b^2*c^3)/(a*d)
