I having some trouble with logarithms again. I am able to solve them okay most of the time. But my final answer answer doesn't match the given one.
Take the following problem for instance. I solved upto
The required answer is,
In this case I see that I could get to the required answer by going flipping the base, 4^1/2 and so on.
In this example I am close to the final answer, but many times I am not this close. Is there a general rule to follow when simplifying? How do I figure out what base the answer should be in? Where should the simplification end?
