What is the base in this problem?

This time the base is *e*. Make sure
that you keep that same base throughout the problem.

***Use the product
rule**

***Use the definition
of logs to simplify**

***1/2 is the exponent needed on e to get e^1/2**

What is the base in this problem?

This time the base is 10. Make sure that you keep that same base
throughout the problem.

***Use the definition
of logs to simplify**

***4 is the exponent needed on 10 to get 10000**

What is the base in this problem?

This time the base is 3. Make sure that you keep that same base
throughout the problem.

***Use the product
rule and the quotient
rule**

***Use the power
rule**

What is the base in this problem?

This time the base is *e*. Make sure

***Use the ** **quotient
rule**

Note that the calculator can only evaluate logs that are base 10 or
base *e*. Since this problem is in base
1.5, we need to change the base to base *e* (or base 10). Since the instructions say base *e*,
let's do that.

***Use the calculator to find ln 20 and ln 1.5**

***Divide**
