To solve an exponential equation,
first change it to log form.
To solve an exponential equation,
first change it to log form.
log3(17) = b
Then solve the log form like we did on previous problems
log3(17) = 
To solve an exponential equation,
first change it to log form.
log3(17) = b
Then solve the log form like we did on previous problems
log3(17) = log(17) = 
To solve an exponential equation,
first change it to log form.
    log(3)
log3(17) = b
Then solve the log form like we did on previous problems
log3(17) = log(17) = 
To solve an exponential equation,
first change it to log form.
    log(3)
log3(17) = b
Enter your answer.
Round to the nearest hundreth
(two decimal places like 3.42)
What does our answer mean?
b =2.58
This means that 32.58 = 17
Solve each exponential equation
First, change this equation to log form
log    (       ) = r
Round to the nearest hundreth (2 decimal places)
Solve each exponential equation
First, change this equation to log form
r =
Now solve the logarithm using a calculator
log12 ( 13  ) = r
Then use a calculator to evaluate the log
