Teaching GuideMathematical Goals • Write and simplify expressions with rational numbers and exponents At a GlanceThe process for finding powers of rational numbers is the same as theprocess for finding powers of whole numbers.
Summarize the example by asking:
• How can you write repeated products of two different numbers, such as1.2 3 1.2 3 1.2 3 7.5 3 7.5, using exponents? Summarize the example by asking: • Can you use the rule for multiplying two powers to simplify theexpression ?• Can you use the rule for multiplying two powers to simplify theexpression 42 3 52? a.
