Exercise 2 Page 347

What does the Zero Exponent Property say? How about the Negative Exponent Property?

1/d^4

Practice makes perfect

To simplify the given exponential expression, we will use two Properties of Exponents. The first one is the Zero Exponent Property.

Zero Exponent Property
a^0=1, for every nonzero number a

We will also use the Negative Exponent Property.

Negative Exponent Property
a^(- n)=1/a^n, for every nonzero number a

Let's simplify the given expression using these properties.

d^0* d^(- 4)

NegExponentToFrac

a^(- m)=1/a^m

d^0 * 1/d^4

a^0=1

1 * 1/d^4

Identity Property of Multiplication

1/d^4
