Although this calculator says "infinity", you can get a better answer by using logs.

Let  x  =  72015

Then  log(x)  =  log(72015)

--->   log(x)  =  2015┬Ělog(7)

--->   log(x)  =  1702.87   (approx)

--->   x  =  101702.87

Since 10.87 is approximately 7, 

the value is a 7 followed by 1702 zeros (approximately).
