One of the rules of logarithms is as follows;
We can now insert the corresponding values in the question provided, as shown below;
Note that, one of the rules of exponents, states that a number when raised to the power of a negative value, is equivalent to the reciprocal of that expression. An example is shown below;
Therefore, our equation can now be re-written as follows;
However, the question requires the answer to be expressed in exponential form. Therefore,
Try graphing the 3 first (you know it's positive 3 because it has a + before it, and you know the line is going to go down (negative) because it has a - before it, after that you can find the slope if the line, in this case 1/2, and move one unit down (because it's negative) and 2 to the right
