2.Solve each of the following equations. a) 5x−2 = 4 Solution 1. We re-write the exponential expression first: 5x−2 = 5x 52 = 5x 25 5x−2 = 4 5x 25 = 4 multiply by 25 5x = 100 x = log 5 100 So the solution is log 5 100. Please note that the final answer can be represented in numerous ways. For example, log 5 100 can be re-written as ln100 ln5
