1 Solve 3^2x-1 = 27, showing steps as done above.

2 Solve 3^{x^2 - 3x} = 81, showing work as done above.

3 Solve 4^x+1 = 64, showing steps as done above.

4 Solve 4^x+1 = 1/64, showing work as done above. Hint: 1/64 = 4^-3

B Solve the following showing all steps as done in the examples in the lesson content. (See Exs. 1-4)
