Question

Simplify x^0yz^-3. Please explain

Answer 1

Answer: $\frac{y}{z^3}$

Step-by-step explanation:

To simplify the expression given in the problem, you must apply the proccedure shown below:

1- According the Exponents Rules, you know the following:

$a^0=1\\\\a^{-n}=\frac{1}{a^n}$

2- Therefore, keeping the above on mind, you can simplify the expression given in the problem as you can see below:

$x^0yz^{-3}=(1)yz^{-3}\\\\=yz^{-3}\\\\=y\frac{1}{z^3}\\\\=\frac{y}{z^3}$
