How many bits are needed to represent each integer?

The only one I don't get is this one:

3^1000

How are you even supposed to figure that one up?

The answer in the back of the book is 1585 but I don't know how to get it myself.

Which ones did you get?

Solve for 'x'.

It is not a difficult logarithm problem, but I'm not quite sure why 1 was not added to the result.

, but , and that's clearly not 2 binary digits.
