WebMar 22, 2016 · I would imagine the log base being #10# so we write: #log_(10)(0.01)=x# we use the definition of log to write: #10^x=0.01# but #0.01# can be written as: #10^-2# (corresponding to #1/100#). so we get: #10^x=10^-2# to be equal we need that: #x=-2# so: #log_(10)(0.01)=-2# WebI'm not sure how you made that last step. log2 (b) / 2 = log2 (b) / log2 (4) = log4 (b) . To get log2 (b^2) you'll have to arbitrarily multiply log2 (b) / 2 by 4, which is not a legal operation. Regardless, you can use any base you want, unless some particular base allows to simplify the expression further.
