How do logarithmic equations relate to exponential equations?

Logarithmic equations are the inverse of exponential equations.

Say you have the exponential equation of:

This is inversely equivalent to:

By general definition:

=

The difference is 6,050 feet.

To find the difference between the two values, you just have to subtract them.

Our problem is:  5895 - (-155) 

To do this, we change it to 5895 + 155 = 6050
We change it because we are subtract a negative number and subtracting a negative number is the same thing as adding it.
