Exercises Polynomials and factoring

Example 6.62 from Elementary Algebra, 6.5 Divide Monomials

Divide Monomials: example 6.62

Simplify: ⓐ $9^{0}$ ⓑ $n^{0} .$

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution
The definition says any non-zero number raised to the zero power is 1.

ⓐ
Use the definition of the zero exponent. $\begin{matrix} 9^{0} \\ 1 \end{matrix}$

ⓑ
Use the definition of the zero exponent. $\begin{matrix} n^{0} \\ 1 \end{matrix}$

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Simplify: ⓐ $15^{0}$ ⓑ $m^{0} .$
