8^log 8^5

**Reiny**, Sunday, April 7, 2013 at 11:39pmlet x = 8^log8^5

I can't see a way to get an "exact" answer.

by calculator I get appr 11963.5

are you sure the base of the log is not 8 ?

**Kendall**, Sunday, April 7, 2013 at 11:43pmSorry, it says

8^log(8^5)

**Reiny**, Sunday, April 7, 2013 at 11:50pmthen my above answer stands, no "exact" answer other than 8^log(8^5) itself

check:

log 8^5 = log 32768 = 4.515449...

then 8^log (8^5)

= 8^4.51449 = appr 11963.5

I would get an 'exact' answer if the base of the log at the top had been 8.

That is why I questioned your problem.
