Example 1B: Solving Exponential Equations
{"Image DocumentName": "Example 1B: Solving Exponential Equations", "Image ImageDescription": "Solve and check. 4x \u2013 1 = 5. log 4x \u2013 1 = log 5. 5 is not a power of 4, so take the log of both sides. (x \u2013 1)log 4 = log 5. Apply the Power Property of Logarithms. x \u20131 = log5. log4. Divide both sides by log 4. x = 1 + \u2248 log5. log4. Check Use a calculator. The solution is x \u2248", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
