What are the log rules?
The rules apply for any logarithm logbx, except that you have to replace any occurence of e with the new base b. The natural log was defined by equations (1) and (2)….Basic rules for logarithms.
| Rule or special case | Formula |
|---|---|
| Quotient | ln(x/y)=ln(x)−ln(y) |
| Log of power | ln(xy)=yln(x) |
| Log of e | ln(e)=1 |
| Log of one | ln(1)=0 |

How do you solve log powers?
Use the power property of logarithms to simplify the logarithm on the left. Divide both sides by log 4 to get x by itself. Use a calculator to evaluate the logarithms and the quotient. You could have used either the common log or the natural log with the example above.

Why is there no cube root Button on the TI-89?
Note that there is no cube root button on the TI-89. That’s because the user should know a cube root is basically raising to the 1/3 power. I guess the square root is used enough that it warrants its own button. Thanks. They should make the Ti-89s more pH friendly.
