Prepare for quiz Monday 12-13

Quiz on Monday 12-13.  Open notes.  Show your work.

Problems will be chosen from p136 items 1, 2, 4 and p137 items 1, 2, 3.

If you were absent or if you have to make up the quiz, alternate problems will be chosen.

Study hints:

Practice using the change of base procedure of dividing the log to the new base of the argument by the log to the new base of the old base.

Practice "de-exponenting" a variable by taking the logarithm in that base.  This means using the logarithm and exponent functions as inverses of each other to undo the expression so that the exponent appears without the base.

Practice turning both sides of an equation into exponential expressions using the same base.  Do this so you can set the exponents equal to each other.

Practice removing the "log to the base b" symbol from both sides of an equation so you can set the exponents equal to each other.

Know that a base raised to an exponent equals an argument, and that the log to the base of an argument equals an exponent.
