2. Look at the way the following exponential equation was solved for x. Somewhere in the steps, an error was made. Equation: 5^x-4 = (1/125)^2x+1. Steps: 1: 5^x-4 = (5^3)^2x+1. 2: 5^x-4 = 5^6x+3. 3: x-4=6x+3. 4: -5x -4 = 3. 5: -5x=7. 6: x = -7/5. a. Where was the error made? Pick one: From Step 1 to 2. From Step 2 to 3. From Step 3 to 4. From Step 4 to 5. From Step 5 to 6. Write the specific part of the problem that is wrong here: b. Explain why it is a mistake and what should be done instead. c. Work out the rest of the problem correctly, showing your work step by step.
