Question

what is the answer to numbers 28 and 29 (please show work)

Answer 1

Given:-

The geometric mean of two numbers is 8. one of the numbers is 2.

To find the other number.

So now we use the formula,

$gm=\sqrt[]{xy}$

So no we substitute the values. we get,

$\begin{gathered} 8=\sqrt[]{2y} \\ 8^2=2y \\ 64=2y \\ 32=y \end{gathered}$

So the other number is 32.
