Hello math newbie here. Sorry need to ask this basic question.
What is the answer of
log (base 2) (100000 + 1) - 1
According to my info for log base 2 we divide it by log base 10 (2) for example
5 = log base 2 (32)
Now calculating log base 2 (32)
log base 2 (x) = log base 10 (x) / log base 10 (2)
So
log base 2 (32) = log base 10 (32) / log base 10 (2)
= 5
Now according to the above rule my answer comes out 15.60 i.e,
log (base 2) (100000 + 1) - 1
= log (base 2) (100001)-1
= 16.60 -1 = 15.60
but in my text book this is equal to 20.
Please tell what mistake I am doing?
Thank You!
