By definition:    Log x  = y   then  x=10^y

So

63.65 = log x      then x is a big number:

10^63.65  = x

If 63.65 is log of a number, then it only means to raise that number to power 10 or e:

So, if we use 10 base=10^63.65, which is a huge number consisting of 64 digits long!!.

And if we use e (the base of natural logs), then we have e^63.65, which again is a huge number consisting of 28 digits long!!. You can use calculator and see how big they are. For example, if we try to calculate e^63.65, you will get this huge number:

4,393,835,294,868,530,279,801,868,818.663. And if we use base 10^63.65,then the number is much bigger. Here it is:4466 8359215096 3118556250 5243193766 1637730017 8608014568 2016723523.2761842284.

NOTE: The question might be asking you to find log (63.65)? If that is so, then log(63.65) would be:

1.80379......etc., which is much more likely. Good luck.
