In this section, we will learn to solve equations which contain an exponential or logarithmic function. We will begin by considering two simple equations, (1) 5e x = 11, (2) log (2x) = 3. To solve (1) and (2) we need to find the value(s) of x for which the equations are
(a) Find a formula for the number of bacteria at time t. (b) Find the number of bacteria after one hour. (c) After how many minutes will there be 50 000 bacteria?
To solve logarithmic equation, remember that if two logs with the same base are equal, their insides must also be equal. Example 1 Solve: log2(x – 1) = log2(4). – 1 = 4. = 5 The answer is x = 5. Set the inside of the logs equal to each other. Add 1 to each side. Sometimes you need to combine logs before solving the equation.
