Additional Example 1: Using a Pattern to Simplify Negative Exponents
Simplify. Write in decimal form.
A. 10–2
10–2 = 1
10 • 10
= 1100
= 0.01
B. 10–1
= 0.1
= 110
Extend the pattern from the table.
Multiply. Write as a decimal.

Subtract inside the parentheses.
Evaluate 5 – (6 – 4)–3 + (– 2)0.
Evaluate the exponents.
Additional Example 3: Using the Order of Operations
5 – (6 – 4)–3 + (–2)0
= 5 – (2)–3 + (–2)0
= 5 – + 1 1 8
= 5 7 8
