15. REVIEW 1. Give an example of a factor using squared and cubed. Then evaluate each. EXAMPLE ANSWER: 5 squared is 5 times 5; 5 cubed is 5 times 5 times 5. 5 is the factor since it is being multiplied together to form a product. 5 squared is 25 and 5 cubed is 125. 2. Give an example of a number in exponential form and name the parts. EXAMPLE ANSWER: since numbers written with exponents are in exponential form. Numbers expressed using exponents are called powers. 5 is the base and 2 is the exponent. LESSON REVIEW
