Question

Can someone help me??
Find the geometric mean of the pair of numbers.

242 and 8
A. 44
B. 49
C. 1872
D. 54

Answer 1

multiply the numbers,
then take square root

Answer 2

geometric mean of \(a\) and \(b\) = \(\large \sqrt{a\times b}\)

Answer 3

How would I know if it's a or b??Like...would 242 be a or b??

Answer 4

that's a good question :) the answer is it doesn't matter cuz \(a\times b = b\times a\)

Answer 5

yeah geometric mean is the square root of their mean....

Answer 6

order doesn't matter when you multiply...

Answer 7

Let me see what I get..
\[\sqrt{242*8}\]

Answer 8

Is that what it's going to look like??

Answer 9

Yep !

Answer 10

Ok. So now I have:
\[\sqrt{1936}\]
What do I do next?

Answer 11

simplify :
\(\large \sqrt{242 \times 8 } = \sqrt{121 \times 2 \times 8} = \sqrt{121\times 16} = 11\times 4 = 44\)
