You can use the properties of logarithm to get to the solution.

The approximate value for given term is given by

$log_3(14) \approx 2.402$

<h3>What is logarithm and some of its useful properties?</h3>

When you raise a number with an exponent, there comes a result.

Lets say you get

$a^b = c$

Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows

$b = log_a(c)$

Some properties of logarithm are:

$log_a(b) = log_a(c) \implies b = c\\\\\log_a(b) + log_a(c) = log_a(b \times c)\\\\log_a(b) - log_a(c) = log_a(\frac{b}{c})$

<h3>Using the above properties</h3>

$log_3(2) + log_3(7) = log_3(2 \times 7) = log_3(14)\\\\0.631 + 1.771 = log_3(14)\\\\log_3(14) = 2.402$

Thus,

The approximate value for given term is given by

$log_3(14) \approx 2.402$

Tim - 3x
Marie - 6x
William - x

$\frac{William}{Marie}=\frac{x}{6x}=\frac{1}{6} \Rightarrow 1:6$

M(6, 6) is the midpoint of . The coordinates of S are (8, 9). What are the coordinates of R?

Sidana [21]

$\bf \textit{middle point of 2 points }\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
R&({{ x}}\quad ,&{{ y}})\quad 
% (c,d)
S&({{ 8}}\quad ,&{{ 9}})
\end{array}\qquad
% coordinates of midpoint 
\left(\cfrac{{{ x_2}} + {{ x_1}}}{2}\quad ,\quad \cfrac{{{ y_2}} + {{ y_1}}}{2} \right)$

$\bf \left( \cfrac{8+x}{2}~~,~~\cfrac{9+y}{2} \right)=\stackrel{midpoint}{M(6,6)}\implies 
\begin{cases}
\cfrac{8+x}{2}=6\\\\
8+x=12\\
\boxed{x=4}\\
----------\\
\cfrac{9+y}{2}=6\\\\
9+y=12\\
\boxed{y=3}
\end{cases}$
