How can exponential and logarithmic functions be combined

natulia [17]

Well.. .not exactly what you're asking, but the relationship of them is
${
log_{{ a}}{{ b}}=y \iff {{ a}}^y={{ b}}\qquad\qquad 
% exponential notation 2nd form
{{ a}}^y={{ b}}\iff log_{{ a}}{{ b}}=y 
}$

so... hmm to add some
for example let's say $if\ 5^3=125\textit{ that can be written also as}
\\ \quad \\
log_5(125)=3$
