Let’s Review • Mathematical Properties • Classify Numbers • Multi-Step Equations • Absolute Value • Proportions/Percent of increase/decrease • Inequalities : When to switch sign? • Graphing Standard Form • Slope-Intercept Form • B.A.G.
“I can…” • …convert between expanded form and exponential form • …use the rules of powers(product of powers, quotient of powers, power of powers, power of a product, zero power, negative power) to simplify expressions • M(F&A)-10-3 • M(N&O)-10-3
Vocabulary • Anexponenttells how many times a number(or variable), called the base, is used as a factor. • Numbers that are expressed using exponents are called powers.
Example 1 • Write each expression using exponents • Notice the number of FACTORS
Example 2 • Write each power as a multiplication expression.
Multiplying Monomials… • Can be tricky if you don’t follow the rules over the next couple lessons. • A monomial is a number, variable, or product of numbers and variables. Which are monomials? • Monomials that are numbers are called constants
Product of powers • To multiply two powers that have the same base, add the exponents • Example 3, 4
Power of a Power • To find the power of a power, multiply the exponents • Example 5, 6
Power of a Product • To find the power of a product, find the power of each factor and multiply • Example 7, 8
