```Question 215913
Part 1: Write 169=13^2 in logarithmic form.

{{{log(13,169)=2}}}

Part 11: Write log[1/4](1/64)=3 in exponential form.
{{{(1/4)^3=1/64}}}

You may want to see my own explanation of logarithms!  I gave a fairly complete explanation of this topic, in my own "non-traditional" way, according to my own students it is MUCH easier to understand than the traditional textbooks.

Go to my own website by doing a "Google" or "Bing" search for my last name "Rapalje".  At the top of my Homepage, look for "Basic, Intermediate, and College Algebra: One Step at a Time."  Select "College Algebra" and look for Chapter 4 Logarithms.  In addition to this, the "MATH IN LIVING COLOR" pages have a LOT of these exercises solved in COLOR.  See also my VIDEO explanations in which my own classes were video taped on this subject.   From my Homepage, look for the link "Rapalje Videos in Living Color" and choose "College Algebra".  Then select "College Algebra" and "Logarithms."  I have a LOT of resources about Logarithms on my website, and, just like algebra.com, they are all FREE!!
