Problem 5: Simplify
.
Solution:
if you want the answer in terms of the base 3.
if you want the answer in terms of the base 10.
if you want the answer in terms of the base e.
if you want the answer in terms of the base 5.
Note: None of the above is valid unless a > 0, b> 0, c > 0, and d > 0.
Check: Suppose that a = 2, b = 3, c = 4, and d = 5. Then
