Which expression is NOT equivalent to: 2xyz/8xz
A) y/4
B) 2xyz+1/8xz+1
C) 2y/8
D) 4xy^2z/16xyz

Answer 1

\[\frac{2xyz}{8xz}\]What variables can cross-simplify? x and z.\[\text{So: }\frac{2y}{8}=\frac{y}{4}\]So A is a no.
\[\text{Now simplify the other equations and see if they end up with }\frac{y}{4}\]
