 Many things in life can be modeled by exponential relations  Relationship is not linear, but does follow a pattern (e.g. doubling every time, tripling every time)

 Multiplying Powers of the same base: 2 2 x 2 3 BASE EXPONENT  When it’s the SAME BASE, add exponents, keep base the same

 2 2 x 2 3 = = 2 5 = 2 x 2 x 2 x 2 x 2 = 32

 When it’s the SAME BASE, subtract exponents, keep base the same

 Evaluating a Power of a Power (2 3 ) 2  When you raise one power to another power, multiply the exponents, keep base the same

 (2 3 ) 2 = 2 3x2 = 2 6 = 2 x 2 x 2 x 2 x 2 x 2 = 64
