is the number of digits of . Is it possible to calculate:
Can You help me with this exercise?
...Eek. That is a large number.
You could try "guessing" at values for the answer, then using that guess to put a lower bound and upper bound. For example, if , then .
Don't know if that method'll work but it's the only feasible method I see...problem is you'll have to determine between which two bounds lies between. Have fun with that.
