ESSENTIAL QUESTION How are exponents and multiplication related to each other?

EXPONENTS Exponents: a short hand (abbreviation) for repeated multiplication of a number, Called the base, by itself. EX: 5 x 5 x 5 x 5 is written is the base, and 4 is the exponent or power.

EXPONENTS The exponent only applies to the number next to it. 4x The power only applies to the 9, not the 4x. Any number to the power of zero is equal to 1.

EXPONENTS Multiplying exponents: 5 4 x 5 3 could be written, (5 x 5 x 5 x 5) x (5 x 5 x 5) or 5 x 5 x 5 x 5 x 5 x 5 x 5 Which can be written as 5 7. For multiplication you add the exponents.

EXPONENTS Dividing Exponents = This can be written as: 3 x 3 x 3 x 3 x 3 3 x 3 x 3 x 3 After cancelling 3 1 For division you subtract the exponents
