Kathy Moss · Answer 1

Definition of log:

Log (base b) (x) = y or equivalently

if b^y = x then Log (base b) (x) = y

Given 2^3=8

set x=8, b=2, y=3

take log (to base 2) on both sides, then

log (base 2) 8 = 3

Wesley Cole · Answer 2

Take the natural log of both sides:

ln 2^3 = ln 8, or 3 ln 2 = ln 8, following rules of logs.
