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. |
