Answer 1

You basically set up a proportion here.


\(\Large \color{MidnightBlue}{\rightarrow 8:x::x:162 }\)
\(\Large \color{MidnightBlue}{\rightarrow x^2 = 162*8 }\)
\(\Large \color{MidnightBlue}{\rightarrow x^2 = 1296 }\)
\(\Large \color{MidnightBlue}{\rightarrow x = \sqrt{1296} }\)
\(\Large \color{MidnightBlue}{\rightarrow x = 36 }\)

Answer 2

geometric mean
\[=\sqrt{162 \times 8} = \sqrt{1296} = 36\]
