TermDefinition
log4 16=2 log4 16=2 is just another way of saying 4 to the second power is equal to 16.
logb x=y means... X=b^Y
Write as an exponential equation. log5 25=2 5^2=25
Write as an exponential equation. log7 x=5 7^5=X
Log2√2=1/2 This means 2^1/2=√2.
True or false: The base can be equal to 1 and greater than zero. False. the base can be greater than zero but not equal to one.
solve. log5 x=3 log5 x=3 5^3=x x=125
True or false: logb b^x=x True.
What is the Product Property of Logarithms? logb xy=logb x+logb y
True or false: logb x/y=logb x-logb y True
