LOGARITHM NOTATION Logarithm = Exponent log a b = c a c = b Base “the logarithm is the inverse operation to exponentiation”

LOGARITHM NOTATION Logarithm = Exponent log a b = c a c = b Solution

LOGARITHM NOTATION Logarithm = Exponent log a b = c a c = b Exponent

LOGARITHM NOTATION Logarithm = Exponent log a b = c a c = b Log Sign

SOLVING LOGARITHMS log a b = c a c = b 2 x = 16 log 2 16 = x 2 x 2x 2 =16 log 2 16 = 4

LOGARITHMS IN BACTERIA A scientist is growing bacteria in a petri dish, if she started the experiment with 10 bacteria in the dish and it doubles every hour how long would it take for the petri dish to contain 1 million bacteria?

HOW MANY BACTERIA? X = number of hours 10(2) x = x = log = x log ( ) log (2) = x X = 16.6
