can someone please explain to me, how to work out logs?
e.g. log27 to the power 3 ?
I though the above is 3 because 3x3x3=27 and it takes 3, 3’s to make 27. is this correct?
The definition of logarithm states that if logb(x) = y then by = x. This works for real numbers, not just integers.
In your example, log3(27) = 3, because 33 = 27.
Or your second example: log3(11) = 2.182658…, because 32.182658… = 11.
