So, from 10 minutes down to 2 minutes, the difference is 8 minutes.

if we take 10 to be the 100%, what is 8 off of it in percentage?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
10&100\\
8&x
\end{array}\implies \cfrac{10}{8}=\cfrac{100}{x}\implies x=\cfrac{8\cdot 100}{10}$

Write the equation is logarithmic form 33 = 27

Vikki [24]

$\bf log_{{ a}}{{ b}}=y \iff {{ a}}^y={{ b}}\qquad\qquad 
% exponential notation 2nd form
{{ a}}^y={{ b}}\iff log_{{ a}}{{ b}}=y \\\\
-----------------------------\\\\
33=27\iff 33=3^{\underline{3}}\iff log_3(33)=\underline{3}$
