Chapter 5: Q.96 (page 520)

In the following exercises, simplify each expression using the properties for exponents.
$(a) - 15^{0} (b) - {(15)}^{0}$

Short Answer

Expert verified

The simplified form is:

$\begin{array}{rcl} (a) - 15^{0} & = & 1 \\ (b) - {(15)}^{0} & = & - 1 \end{array}$

Step by step solution

Step 1

The Zero exponent property is defined as $a^{0} = 1, a \neq 0$ .

Step 2

Using the zero exponent property, simplify the expression:

(a) $- 15$ is a non zero number, so,

$\begin{array}{rcl} - 15^{0} & = & {(- 15)}^{0} \\ = & 1 \end{array}$

(b) $15$ is a nonzero number, so,

$\begin{array}{rcl} - {(15)}^{0} & = & - (1) \\ = & - 1 \end{array}$
