Rewrite as: "
" ; 
_______________________
Take note of the following definition of a logarithm:
_______________________
"
" ; ↔ "
" ;
_______________________
in which:
refers to the "base" ;
refers to the "argument" ;
refers to the "exponent" ;
______________________________
As such:
"
"
⇔ "
" ; Solve for "x" ;
_______________
Note:
2⁰ = 1 ;
2¹ = 2 ;
2² = 2 * 2 = 4 ;
2³ = 2 * 2 * 2 = 8 .
___________________
→ "
" ;
→ "
" ; since: "
" ;
→ as such: " x = 3 " ;
______________________
Thus:
"log 2 base 8 " ;
=
.
