Exponential and Log
Equations
Solve the equation 3 5x = 42 for x and use a calculator to give a 4 decimal place approximation answers.
| log 3 5x = log 42 | In order to solve for x, the exponent 5x needs to be
brought down as a factor. This can be done by first applying the log function to both sides of the equa tion. |
| Show work. | Bring the exponent 5x down as a factor by applying the third law of logarithms. |
