Chapter 11: Q20. (page 728)

Simplify each expression.
$\frac{2 x y^{2}}{16 x y z}$

Short Answer

Expert verified

The given expression can be simplified to $\frac{y}{8 z}$ .

Step by step solution

01

Step 1. Simplify rational function.

Let $x, y$ , and $z$ , be polynomials with $x \neq 0$ and $z \neq 0$ .

$\frac{y x}{z x} = \frac{y \cdot x}{z \cdot x} = \frac{y}{z}$

02

Step 2. Factor.

Factor each number and write all powers of variables as products.

$\frac{2 \cdot x \cdot y \cdot y}{2 \cdot 2 \cdot 2 \cdot 2 \cdot x \cdot y \cdot z}$

03

Step 3. Divide.

Divide out common factors.

$\frac{y}{2 \cdot 2 \cdot 2 \cdot z} = \frac{y}{8 z}$

Therefore, the given expression can be simplified to $\frac{y}{8 z}$ .
