Exponents! 3.1 Exponent: The number that indicates how many times you multiply the factor. Base: The number you multiply by. Standard from: The answer! Expanded notation: A way of writing a number a number to show which values are in which places. Exponential form: When the number is written ton the "power" with a base and an exponent. Factored form: 2 to the power of 3 written as 2x2x2. Any number to the power of zero equals ONE!

3.2 Multiplication using exponents! - Keep the base, and ADD the exponents. (y7) (y5) (y3) = y15

3.3 Division using exponents! - Keep the base, and SUBTRACT exponents. x15 divided by x12 = X3  3.4 power of a power property! - when you have one base, and two exponents, that means you keep the base and MULTIPLY exponents. This is also called, equal distribution. (x7)4 = x25

3.5 Calculations with exponents! (BEDMAS) B-start work inside the brackets. E-look for any expressions that contain exponents. D-working from left to right, do division and multiplication in the order they appear. M- A-working from left to right, do addition and subtraction in the order they appear. S- (5+2)2 (7)2 49

3.6 scientific notation! (++) positive move the decimal to teh right. (--) negative, move the decimal to the left.

3.7 Multplication and division using scientific notation! 1)Put then into scientific notation 2) multply or divide them 3) put all powers of ten in brackets. 4) add exponents.
