Evaluating Algebraic Expressions with Exponents

What is the first step in evaluating an expression with exponents?

• Substitute the given value for the variable

• Multiply the base by itself

• Perform the exponent operation

• Carry out any addition or subtraction

What does the exponent in an expression tell us?

• The total value of the expression

• How many times to multiply the base by itself

• How many times to add the base

• How many times to divide the base
