Question

log 55 is the power to which ______ must be raised inorder to produce a value of 55.

Answer 1

If the base isn't stated, then by default the log is base 10

ie

\[\Large \log(55) = \log_{10}(55)\]

Answer 2

the base of the log will also be the base of the exponential expression

Answer 3

Okay thats what I thought but I had to make sure. Thanks:) If not Im thinking it is just "x". 10 sounds like a much more accurate answer.

Answer 4

it's 10 because you would do

\[\Large 10^{\log(55)}\]

which gives 55 as the answer

Answer 5

or put another way, log(55) answers the question: "what is the value of x in \(\Large 10^x = 55\) ?"
