\(\bf
log_{{ a}}{{ b}}=y \iff {{ a}}^y={{ b}}\qquad\qquad
% exponential notation 2nd form
{{ a}}^y={{ b}}\iff log_{{ a}}{{ b}}=y\\
\\ \quad \\
thus\\
----------------------------\\
8^5=32768\qquad \iff\qquad log_8(32768)=5\)
so... notice the example there, with 8
so.. you tell us, what is the relationship then?
