Question 29085
log 256=4
   4

note:the 4 is a little 4 after the log


If N is a strictly positive number (N cannot be zero and N cannot be negative)
then the logarithm of N to a given base b is the power p to which the base has to be raised to give the number.
we write  log(N) = p  implies and is implied by (N) = (b)^p
             b 

Therefore   log 256=4   written in the exponential form is    256 =(4)^4 
               4
