Exponential and Log
Equations
i) Find the exact solution to the equation log 3
(x+3) + log 3 (x+5) = 1
ii) Use a calculator to find a 4 decimal approximation to the
answer.
| log 3 [(x+3)(x+5)] = 1 | Prepare the equation for the application of the
inverse log function by making the left side into the log of a single expression (i.e. apply the first law of logarithms.) |
| Show work. | Apply the inverse log base 3 function to both sides. |
