Question

Find the geometric mean of 5 and 8. If necessary, give the answer in simplest radical form.

Answer 1

multiply the 2 numbers then find the square root of the result

Answer 2

5 x 8=40
\[\sqrt{40}=2\sqrt{10}\]

Answer 3

do you know how to simplify square roots?

Answer 4

no

Answer 5

okay then,
to simply a square root you have to look for any square factors like 4,9,16,25 etc
for example the \[\sqrt{40}\] it has one square factor, 4
4 x 10 =40
and the square root of 4 is 2 so it is written as \[2\sqrt{10}\]
the square root of the 4 goes outside and what remains stays under the radical

Answer 6

oh ok thank you again
